Vibration between 45 and 55 MPH

I'm aware that you must receive thousands of individual truck problem questions, but I really need your help on this one. I have a Dodge Ram 1500 WS with a 3.9-liter V6. It has an annoying vibration between 45 and 55 MPH. Symptoms are a lot like bad U-joints, but the U-joints are fine and the truck only has 4000 miles on it. I've had the drive shaft rebalanced and that helped a little, but the vibration is still there.


I'm having difficulty with the dealer, and even the district representative stated that "yours is better than most". I'm hoping that you can shed some light on this problem. It just shouldn't be doing this.




If this is a significant vibration, and both you and the dealer are certain the problem is originating from the driveline, it's time to check the drive shaft angles.


But first, here's some stuff that you might want to try yourself. Unbolt the drive shaft from the rear axle, rotate it 180 degrees and then reinstall it on the rear axle flange. Sometimes this is a quick fix that will synchronize the shaft and axle balance.


While you're there, check the drive shaft "phasing". In other words, when one yoke is straight up and down, the one on the other end should be pointing in exactly the same direction. If not, this would indicate a "torque twist" of the drive shaft tube which will require replacement of the driveshaft.


Also, a drive shaft may balance correctly, but still cause problems due to excessive "run out". This also would require replacement.


Next, venture back to your dealer's service department and politely suggest the inspection of the vehicle ride height, and drive shaft vertical and horizontal angles. They should have the tools and specifications to do this procedure correctly. Any needed adjustments are obtained by the replacement of leaf springs, or the repositioning of the rear axle with the use of selected shims. Excessive improper angles (with correct ride height) which cannot be corrected through adjustment would strongly indicate frame, suspension or crossmember damage.

Dodge Ram 1500 V6 4x2 Auto - When the vehicle gets to 60mph + it starts to shake. I wondered if that a problem with the alignment or if the drive shaft needs to be re-balanced?

Thank you,

Bruno (214) 564-4177

Typically an alignment problem won't cause a shake, but a worn out suspension part can cause an earthquake.

If the steering wheel shimmies you know the problem is in the front. If that's the case, rotate the tires to prove or eliminate them as a cause.

If the shake occurs only while accelerating, that usually points to a driveline issue -- could be a bad u-joint, wrong ride-height, or an out-of-balance shaft.

It's a process of elimination -- get to work.

Same problem as Bruno. I have a 1994 Dodge Ram 5.2 v8 long bed, standard cab, 5 speed, 2wd. The rear shakes a little at 55 to 60 and is not noticeable at 65mph. I tried new tires, new rims, inspected the frame and I still can't figure out what the hell it is.
27 Jul 2010, 20:18
Inspect a little more.

A good start is to put the transmission in neutral while you're experiencing the problem. If the vibration stops it's in the driveline. If it doesn't it's at the wheels.

Wheels meaning it could be a bent axle causing the wheels to turn untrue. You also have to be sure there is nothing loose in the rear suspension and the shocks are in good condition.

You can jack the rear end off the ground and spin the wheels to make sure the tires and wheels are turning straight (no excessive run-out).

I have '06 1500 quad cab that vibrates at various speeds above 45. I balanced the old tires and did an alignment to no a avail. I replaced the tires, did not help. Been to the dealer three times, but they can't find any issues. Then they blamed the tires, which were e rated. Told me that caused the problem. This makes no sense as I have had e rated tire on my other trucks with no problems. The problem feels like u-joints but they were fine. I'm at wits end. Any ideas
28 Mar 2011, 19:41
Best way to prove or disprove the tires are at fault is to swap with known-good wheels from a symptom free truck.

Hello I have a 2000 RAM 2500 5.9L v8. Whenever I go above 45 mph it shakes violantly until you Damn near stop. Wheel bearings, ball joins, u-joints are all in check out OK, but it seems to stick in 4 wheel. Wondering if you have any ideas of what it might be? It does have a 4" suspension lift.
19 Feb 2012, 13:56
Sticks in 4WD? Might be a good idea to fix that problem first.

If the problem is only present in 4WD, I would carefully inspect the front drive axle, engine/transmission mounts, etc.

And yes, a suspension lift improperly installed can affect the driveline angles and cause a vibration. Did the problem begin immediately after the lift install? Or you don't know?

I have a 2009 Ram 1500 4x4, has steering wheel and gas pedal vibration starting at 35mph is worse at 40 gets less at 60. I put the trans in neutral, vibration still there, not the drive train. Turn to the right and the noise and vibration go away, back to center starts again. Has something to do with something spinning with speed and steering linkage. Tie rod ends replaced under recall. No abnormal tire wear 45k miles. any ideas?
12 Aug 2012, 15:48
Sounds like either a tire or wheel bearing. Start by rotating the tires to see if there is a change.

Still the same? Make sure there is no play in the bearings by rocking the wheels.

After that, the best way is getting all 4 wheels off the grounds and listen to each bearing with a a stethoscope while spinning the wheels. If it's much louder on one side -- that's the culprit.

I can not keep a clutch in my 1995 Dodge

Keep a clutch?

If you mean it wears out quickly, that requires removal and a full inspection of all parts to diagnose the problem.

But in the mean time be sure you have about an inch of freeplay at the pedal. The master, slave or hose can be hanging up and you're riding the clutch with your foot off the pedal.

14 Apr 2013, 12:40
Vibration only on acceleration is typically a problem in the driveline. However, I have seen tires do a good impersonation.

On a 2WD truck, if you feel the vibration distinctly in the steering wheel, the problem is in the front end.

If you feel it from the seat-of-your pants, take a careful look at the drive shaft and rear suspension.

There was a pre-delivery recall for defects in the driveshaft, and anything messed up in the rear suspension can throw off the driveline angle and cause a vibration.

You didn't lower or raise the suspension, did you?

04 Jun 2013, 01:02
I have a 93 jeep yj I get it up to 35-45 mph it shakes horribly, but if I push the clutch it all stops any ideas???
23 Jun 2013, 13:43
First think to check is both front and rear drive shafts. Possible worn out U-joints. Vibration stopping when disengaging the clutch typically confirms a problem in the driveline -- not the wheels or tires.
08 Jul 2013, 01:26
2004 2500 4x4 5.7l. 150k. About 2 weeks ago front end vibration started. vibration through steering wheel and dash (shakes drinks in cup holders) vibration stops near instantly when trans put in neutral or letting off the the throttle. vibration starts at about 25mph gets a bit worse up to about 45 and tapers off to near normal at 60-65. no lift on truck.
19 Jul 2013, 19:05
Feeling it in the steering wheel tells us the problem is up front. The vibration going away in neutral tells us it's in the driveline.

Carefully inspect the front axle, front suspension, and especially the front driveshaft! Could be a worn U-joint.

Okay, I have a used Ram 3500 maxi van(old church bus) that vibrates under light acceleration @40mph,up to 70mph, and is light and continuous at 80+...
360V8,9.25 Chrysler corporate LSD with 3:92 gears, @90,000 miles now...had drive shaft pulled and inspected and echanic said it was ok,has weak shocks all the way around, mech. said probably second set.
If I throw it in neutral, the vibe stops...if I let off gas vibe stops, if I step on gas hard, it usually stops and powers through...I had the rear gear oil changed and anti friction additive repalced and the mech inspected the gears and felt they were fine as there was no odd scratches, chips or metal filings in the housing.
I love this old beast and intend to install a bed anc rooftop a/c so the wife and I can go camping with it, but all is on hold until I get this vibe issue worked out...oh and when I bought it last year, there was a trouble code for the fuel sensor...as the fuel gaugedoes not work well...usually reads empty sometimes even after a full fill up.
I know y'all are busy, but I'd really appreciate some help here.
Thank you much,
16 Oct 2013, 12:23
Must be sure tires are good, and all suspension parts are tight. Shocks could be an issue if they are completely gone.

But the vibration stopping in neutral or foot-off-the-gas are classic symptoms of a driveline problem.

Double check the driveshaft(s) and u-joints. Also the center support bearing if equipped. Be sure engine and transmission mounts are not broken, and no suspension modifications which would change the driveline angle are attached.

Hey there'
Thanks for the reply. I will be changing the rear shocks next week, and working on tire replacement. After that, front shocks will be replaced...all thiss stuff is a must. After all that, I will have the mechanic check all the suspension parts, and then have the drive shaft ballance checked, and u-joints replaced as part of maint. since it is nearing 100,000 mile mark.

There is one thing i neglected to mention though...the door info decal calls for 245-16-75 tires on the thing, but it has 265-16-75's...that will change as soon as I can.
Thanx again,
24 Oct 2013, 20:39
Keep me updated. Again, sure sounds like driveline.

I have a 99 dodge Dakota 4x4
When im at 55mph I feel a slight vibration. When I accelerate I feel it the worst. Any suggestions?
Also, when I am at a stop and I turn the steering wheel all the way hard left and slowly move forward, I hear a grind noise in the drivers side front end. Almost like the tire is rubbing on wheel well, but is not. And every time the tire rotates it feels as if it wants to stop the truck at a very slow speed. Shoud I use a grenade or a missile launcher?
31 Oct 2013, 16:34
I have just replaced passenger side front axle, pads and passenger side tie rod end.
03 Nov 2013, 09:59
Read above. Gotta check everything. Rotate the tires to eliminate that. Could still be the LF axle, or coming from the rear driveline.
03 Nov 2013, 20:06
02 Dodge Ram 1500 quad cab 2wd 4.7l V8 - when I hit 50mph on the dot the truck starts shaking throughout from bumper to bumper, not terrible but not delightful to feel or listen to. have had tires rotated and changed to no avail over several years. truck does need a new CPU, could that be the issue? also when driving 15mph+ the front end sqeaks terribley and even more when breaking, could it be the rotors or the wheel barrings or front axle? and lastly, the AC works but doesn't blow cold air during the summer, during spring and fall its fine but during summer it blows heat.?
04 Nov 2013, 07:58
The grinding in the front end was coming from my outer tie rod end rubbing on the inside of my rim.
Still yet to change out U-joints.

Only between 55 & 60ish mph is when I feel the vibration. Only when accelerating... I also have a spare tire on my back drivers side that is bigger then the rest.
09 Nov 2013, 09:25
Either wrong wheels, wrong or switched (left to right) tie rod ends typically produce tie rod to wheel contact.

I have a 06 ram 2500 short bed quad cab 4x4 with 5.9L Cummins has a 5"lift 35" tires new upper and lower ball joints new front and back u joints new upgraded steering linkage steering box is new.also new adjustable trac bar. Also has a steering gear box stabilizer. Tires are new. The problem that I'm having is when I get to freeway speed i hear this shuddering noise like plastic is rubbing against something I've taking all the plastic off and still getting the noise sometimes it does it more when going through dips. Its driving me insane. Any suggestions

12 Nov 2013, 19:50
What plastic have you removed? Does it seem like the noise increases with vehicle (wind) speed?

Try taping off sections around the windshield moldings, and any other place you can think of. Loose moldings can lift up and flutter at high speeds.

99 dodge Dakota 4x4 is got a bad vibration when accelerating. Coming to a stop then accelerating it vibrates underneath and sometime feel it shaking the steering wheel. Then stops when I let off the gas pedal.
17 Nov 2013, 09:17
Gotta start by getting under the truck and doing a detailed inspection of the suspension and driveline -- the front driveshaft/U-joints especially.

17 Nov 2013, 21:48
It was in fact my U-joints... The vibration is gone. Much appreciated for all the tips. Thanks again and god bless

I recently put new tie rods, tie rod ends, and upper and lower ball joints in my 1998 Dodge Dakota 4x4 and now the wheels rub on the outer tie rod ends when the steering wheel is turned hard over. how can I fix this? thanks.
01 Dec 2013, 09:33
Either the wrong outer tie rod ends, or you have the left and right ends on the wrong sides (reversed).

04 Dobge Ram 1500 Qwad at 55 as lond as I keep my foot on the gas I dont fill the vibration but as soon as I take my foot off I fill it in my seat, Also I hear a bump , bump from the back driver side tire at about 5 to 10 mpr, one last thing my back driverside shock had broken from the bottom weld and is just hanging, Can this throw the U-Joint off and cause the problem.
14 Feb 2014, 07:53

You have to fix the broken shock, and figure out the low speed "bump,bump" noise, before doing anything.

Maybe get it to a local shop, and let them look it over.

I have 2001 1500 2 wheel drive, the vibration is in the engine, I pulled off clutch fan and blade, still have a vibration at 1000 to 1800 rpm, not sure what it is, vibration damper?
19 Feb 2014, 09:49
03 dakota 3.9 4x4. Mild vibration at 50 mph that gets terrible(under seat) above 63mph. At 63 and let off throttle vibration gets worse. Makes no difference if put into neutral.
28 Feb 2014, 19:16
I have a 2005 Dodge 2500 5.9L diesel. My steering wheel shakes at 55-70 mph-(worse at 60-65). When I am at a coasting speed the shaking starts. If I let OFF the gas it QUITS. I dive real hard to the left at 60 mph, the shaking quits and if I dive to the right, the shaking starts again. If I let off the gas it quits ---- all this only above 50mph. The dealer replaced the front steering linkage, transfer case, torque converter, and went thru the front axle looking for bad bearings and u joints, also checked pinion bearing, all at my expense---still not fixed. Now they are looking into the motor and expect me to also pay for any parts they think I need! DON'T KNOW WHAT TO DO NEXT --TRUCK IS STILL IN THE SHOP going on 3 weeks.
14 Mar 2014, 14:36
RE: robert
15 Feb 2014, 18:27

First thing I'd look for is a hard or broken engine mount. Does the vibration change from reverse to drive?

Look for a wobble, or rubber malformed between the inner hub and outer pulley of the damper.

Can also try rotating the torque converter one bolt hole at a time to see if that makes the vibration better or worse.

Again, engine mounts first.
14 Mar 2014, 14:40
RE: jordan
19 Feb 2014, 09:49

Hey Man. Gotta start with a careful visual inspection of the front and rear driveshafts and axles, along with all four tires and wheels.

Nuff said.
14 Mar 2014, 15:05
RE: Brian
28 Feb 2014, 19:16

I think you need to take it somewhere else.

Hopefully wheels and tires have been absolutely eliminated as a cause.

Other than that, they're missing something at the front suspension and/or axle/driveshaft.

Double check the front driveshaft's u-joints, "phase", angle, and balance.

Hi. I have a 2005 Dodge Ram 1500 4x2 Q.C.sport with the 5.7 hemi and auto trans and 3.92 axle which I recently purchased with 115k miles. I have installed new brakes (original rotors turned) all around, 4 new shocks,water pump, radiator, idler and tensioner pulleys, and front and rear u joints all within the last few weeks. The issue I have is that at WOT a fairly loud "roaring" vibration becomes noticeable briefly at around 4000rpm, then fades and comes back in at 5000rpm and stays until the trans shifts into the next gear at 57-5800rpm.Also, the "frequency" of this vibration increases as the rpm's increase. As soon as the trans shifts and rpm's drop the sound stops until rpm's reach 5000 again.Happens in any gear at various speeds, but tends to be louder in 1st to 2nd gear runs.?.? Truck runs and drives fine otherwise. Maybe the torque convertor? Fan clutch? Balancer? It had a really loose front u joint (until it was replaced) with which it was driven for a while by the previous owner, i think. Maybe the tailshaft bearing/bushing bad? What do you think? thanks!

2001 Dodge Ram 1500 - shakes violently 45-60 while accelerating. The key seems to be turning off the OD. It stops immediately. Turn OD back on, shaking starts again. Is the OD and indicator that will help narrow down the search? Thanks!

'01 Ram 4x4 3500, diesel, DRW. A vibration and noise from front area that starts around 55-60 mph, but seems to fade at 70 mph. If put in neutral to coast, the noise/vibration is still present, but not as pronounced. Eliminated any engine possibilities as noise/vibration does not present itself throughout the same rpm range going up the 5 spd manual until at highway speeds.
What is odd is that it is not a constant steady noise, but more oscillating. And I recently found if while at highway speed I can get the noise to stop for a second or two if abruptly moving from one lane to the other, as if slaloming. Just had new tires installed, and alignment checked. The ball joints had .030" of travel, which Moog tech support said was at most outer accepted tolerance, but still usable. I am leaning towards the unit bearings going bad, which were bought from the dealership only 40k miles ago. Or could the slight angle from the .030" offset cause the axle shafts to ride untrue internally? The previous ball joints had more than twice that amount and never heard any kind of noises. I just wanted to ask as these bearings are not cheap if not needing to be replaced. Thank you for your help.

'03 Ram 1500 4X4 4.7L Quad Cab
190K miles
Vibration starts only at speeds above 65mph and continues / worsens at higher speeds, vibration seems to be coming from the rear as I can't feel it in the steering wheel. It also continues after putting the truck into neutral until speed drops below 65, I have had the rear driveshaft balanced, Installed new "U" joints, new rims and tires installed, drive shaft balanced again and another set of "better" tires installed. This is a great truck and I don't drive it frequently on the expressway, however when I do need to drive it above 65mph it is VERY annoying not to mention I am afraid the vibration may be causing other problems such as excessive wear & tear on new tires. Could the problem be a slightly bent rear axle, worn bearing(s), rear differential.. ?? How do I proceed from here? Thanks for any help /guidance on this
13 Jul 2014, 10:13
RE: Chuck Stillson
14 Mar 2014, 20:14

Hi Chuck if you feel the vibration on acceleration it is most likely a drive line problem. Have a mechanic check the drive shafts for bad universal joints or drive shaft balance. If joints are good try turning the drive shaft 180 degrees, sometimes this helps Cordiant the shaft and axel balance.
13 Jul 2014, 10:20
RE: J. Campbell
25 Mar 2014, 15:26

I would check the clutch fan first to see if it is locked up. This can cause a roaring noise at high engine RPM's. The torque converter won't make a noise. Try rotating the drive shaft 189 degrees, sometimes this coordinates the balance between the drive shaft and the rear axel.
13 Jul 2014, 10:35
23 May 2014

It's could be one or a combination of three things, the speed sensor, the Torque Converter, or the OD. Have a mechanic use a scanner to observe the function of these three items. If the truck has a lot of miles on it you can also check the function of the TPS sensor, it has a lot to do with shifting.
13 Jul 2014, 10:43
Mike G
25 May 2014

Try rotating the tires from front to rear to see if the condition changes. If it is still the same then put the truck in the air and check the bearings with a stethoscope to see which side the noise is coming from. It is possible it could be the bearing again.
13 Jul 2014, 10:53
RE: Rick R
25 Jun 2014

Putting the truck in neutral almost eliminates the drive line but to be sure the drive shaft angles would be the next thing to check and also the run out of the drive shaft and the axels. Jacking up the rear wheels and have someone watch the wheels turning can help find a wheel wobble or bent axel. Try turning the drive shaft 180 degrees to see if it changes anything, sometimes this coordinate's the balance of the drive shaft and the rear axel.

RE: Andrew, Check the front end for wear. Check ball joints, sway bar bushings and links, tie rods inner and outer, upper and lower control arm bushings. Also check the rear leaf spring bushings and mounts, and be sure there is not a broken leaf in the spring.
15 Oct 2014, 20:34
RE: Andrew: Also check the drive shaft universal joints and drive shaft angle.
15 Oct 2014, 20:36
RE: Mari Moreno, Have a mechanic check the engine to see if it firing on all cylinders. A cylinder misfire can cause this problem.
15 Oct 2014, 20:43
RE: Jay, You can try to remove the drive shaft from the rear end and put it back in 180 degrees from the position it was removed from. Sometimes this can change the balance and remedy the problem. If it doesn't work check the balance of the drive shaft.
15 Oct 2014, 20:47
Re: John, You will most likely not have any play in the bearing but the bearing is pitted inside making the humming sound you are hearing. This is indicated when you say the noise goes away when you go into curves to the right and it goes away.

Hello, I have a 2014 Dodge Ram 3500 4x4 Laramie Diesel. I took off the original tires and rims and replaced the with Fuel Tires and Fuel rims. Then the truck started to shake. The dealer changed the tires due to one being defective. The second time the dealer changed the rims because one was defective. The third time the dealer changed the rims and tires and the truck shook only at 68 to 72mph. Then we placed my girlfriend's tires and rims on, since she has the same truck, she has cooled tires and fuel rims, and the shake went away. We replaced the tires and rims with stock tires and stock rims and no more shakes. When we replaced the rims and tires with the fuel rims and Toyo tires the shake returned. What to do?

Hello. Sorry for mistakes. That was Cooper Tires on my girlfriend's truck. I also had the truck leveled with a kit
20 Oct 2014, 09:35
The problem is obviously with the tires and or rims. You should go to where you bought them and see what they can do. Re balancing the tire (s) and checking the rims for out of round would be the first step.
20 Oct 2014, 22:08
Look for a high tech shop that has tire balancing equipment that can measure the tire force variation measurement. Smooth road highway shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed.

The tires should be checked for balance again to rule out any balance problem and also check what they call "Tire Force Variation" and check all rims for out or round run out or any rim that is bent. Check this if the vibration appeared only after the new tires were put on. There is a service bulletin on the front hubs that mentions if the truck was in a collision that included front suspension damage the hubs should be inspected or replaced. There shouldn't be any play in the hub assembly from what I know of. Make sure the axle shaft nut is tight and there are no other front end issues.

I have a 2014 dodge ram 1500. When I'm driving around 48-50 or over miles, I start to feel vibration. They already replaced, the drive shaft, and rebalanced the tires, and changed all the tires, and rims, but there is still vibration. What else could be the problem? Have any suggestions? Please help me. You can email me @ ednamaefelix@yahoo.com. Thank you, I really appreciate it.

You should find a shop that has a wheel balancing machine that can check a condition called wheel force variation as well as tire and wheel run out.

It is also important to be sure where you feel the vibration. Does the vibration feel like it is in the steering wheel or does it feel more like it is coming form the body, you would feel it in the seat more than the steering wheel.

A good repair shop will use a tool called a reed tachometer. This is placed on the dash board and help diagnosis the vibration by detecting the frequency of the vibration. This can help the technician locate the area of the vibration.

Try these suggestions and get back to us with your results.

I have an 01 Dodge Ram 1500 QCSB 4x4 with a 5 speed NV3500 Transmission have a bad grabbing when coming to a complete stop, a whine in the rear end when reversing and a loud clunk when first moving. Checked the rear brake adjustment, no change Checked the u-joints they had a little play so i replaced them, the problems got worse I am thinking maybe ring and pinion gear, No Lift and running 265/75/16 Load range E tires
Does this whether I am turning or not
Any Ideas
04 Dec 2014, 15:33
RE: Dillon, This may be in the rear end (differential). Take the drive shaft off and see if there is any play at the pinion flange, if you do then take the rear differential cover off and see if there is metal in the gear oil, the problem may be worn pinion bearings and if you do have metal in the gear oil then you are looking at an overhaul of the rear end.

Hi, 06 ram2500 4x4 diesel shortbox quad cab. Vibration felt in accelerator pedal, only around 60 KMH, and 110KMH. New brakes all round, front upper and lower BJ's, front axel UJ's, and front driveshaft taken off; all with no change. Also occurs with winter or summer tires. Is this front wheel bearing?
08 Dec 2014, 15:57
Front wheel bearings could cause this but you would usually hear a growling noise also when putting weight to one side of the truck like turning or changing lanes. The best way to check wheel bearings is to put the truck on a rack and run the truck in gear and listen to each wheel bearing with a stethoscope. This will help you pin point which bearing is bad.

The rear universal joints could also be the problem and the rear drive shaft should be removed and inspected.

When you feel the vibration in the gas pedal notice the engine RPM when the vibration happens; put the truck in neutral and see if the vibration changes at the pedal. If the vibration stays the same it may be the bearings. If the vibration changes with engine RPM and the same speed then check the engine mounts, transmissions mounts and throttle cable routing.

I had the same issue, between 45 and 55 a shake/shim. Turned out to be spark plugs and wires
11 Jan 2015, 10:28
RE: Scott Witt, Spark plugs and wires could cause this but if you put the truck into that speed other problems could be causing the vibration like a bad universal joint, bent drive shaft, wheel balance or bad tire and or the drive shaft angle is beyond specs.

Thank you for the information it will help other people to look further than the above list to help diagnosis this problem.

I have a 2001 dodge ram 1500 quad cab 2 X 4 with 59k miles 5 spd manual trans. I have a humming condition under the cab which starts at 42 mph. Wheel bearing have been checked out, Universal joint has checked out, new shocks on the front,Leak Detection Pump just installed,New tires recently put on and mechanic actually placed truck in the air and had truck running at 45 mph and couldn't find anything under the truck that is lose or in need of repair. The humming sounds like new snow tires on dry pavement and no vibrations. You can barely feel something (no vibrations) in the steering wheel at 42 mph but nothing as relevant as the humming.

I have a 98 ram with a 5.9 and I wether through that shaking issue. I'd take over drive off and it would stop shaking. I changed plugs and wires and took the shaking away. So for all those comments about i" it's the u joint" is a line of bulls bullshit. I'm speaking from experience lol how many of you are actually speaking from experience?? Haha from the sounds of it not a lot of you at all lol. Change plugs an wires and promise it will take the shaking away. But if you want to listen to a lot of the idiots on here go ahead and drop a lot of money where the problem isn't lol.
28 Jan 2015, 20:32
RE: Scott Witt, Did the mechanic check the wheel bearings with a stethoscope? The only way to check the bearings is with this tool. It is put on the bearing housing and it can listen to the bearing and you can compare it to the others to determine the exact bearing making the noise.

Hello, I have a 2006 dodge dakota st 2wd.I am hearing vibrations (not feeling them) at around 40mph. I have replaced both wheel hubs lower ball joints as well as tie rod ends. I'm not sure what nor where this noise is coming from. I do believe it is coming from the front right side... Any ideas you could throw my way would be very helpful. Than you
30 Jan 2015, 10:10
RE: Chris Chateauneuf, What are the conditions of your tires if they have feathered tread or have cupping in the tread area then this could be your noise. If your tires look like this try to rotate the tires and see if the noise is in a different area of the truck. If it is different then change the tires.

The tire wear can usually be repaired by a wheel alignment an or wheel balancing if this is wearing the tires.

Put the truck up on a rack by a mechanic and see if the noise is evident with the truck in the air. If you still hear it then use a stethoscope to try to pin point the area of the noise.

I have a 2003 3500 160k miles Cummins auto dually and at around 40-50 mph on certain areas of the road, not all the time, the passenger front wheel starts hopping violently and it's hard to control vehicle. it is similar to what happened when I had a blowout a while back. All tires are new, had them rotated and rebalanced because of bowncing. I have inspected the ball joints, etc and everything looks pretty tight. Could this be caused by shocks (passenger side is a little oil wet and dirt caked.) Any thoughts?
27 Mar 2015, 07:46
Shocks are not known to cause vibration but at 150,000 miles how old are they?

A bad shock that has no oil in it could have some responsibility for this but I would check the front end further. There are tie rods, pitman arm, idler arm, center link, upper and lower control arm bushings that all can contribute to this problem. If the shocks are really old then that is a no brainer to have them changed. Check the front end further that is where the problem sounds like it is coming from.
27 Mar 2015, 15:47
Ok, I would not even be wasting my time here and explaining this to the "experts" except that it might help someone like me and the others that are being bullshitted and lied to in guise of "knowledge." After posting yesterday and before I received my generic "beats me," answer from techhelp2, I went to YouTube and found a TON of great info. First off, death wobble can be caused by MANY different issues, but usually that is the problem, there are usually several very small (or large too) problems. They then all join together to magnify each other. The main issues are the Tie rod configuration along with it's undersize/stregth, frame flex, steering gear wear/weakness, and a worn steering column bushing. I'm not going over all of the "other," or the possible driveline causes of vibration, as this forum has that covered.

Ok, first off, the obvious, which is that there is a tie rod assembly recall for 2003-2013 models of 2500 & 3500 (a few qc 1500's too), so hello! Dodge offers a kit called, "Mopar steering upgrade." The actual bar and ends are substantially larger and are actually a different configuration that helps to eliminate the flexion in the rods that helps start the "death wobble" process. The kit comes with a new pitman arm and steering dampner it's about $400.00, but with the recall, might get Dodge to spring for at least part. (I did). The next items are all addressed at once. There's a kit for $75-125.00 that is called "steering gear support bearing," or "steering stabilizer brace," and fixes a couple issues at once. One of the issues, flexing of the frame, is fixed as this is a bolt in crossmember that keeps the frame extentions from flexing. It also supports the new steering gear box shaft, as this gets worn and instead of just turning, it wiggles a little, allowing play in the system. It may be necessary to replace the steering gear, but not always, as this bearing can eliminate most flexation. You might have to adjust the worm gear though. The final issue that may be adding to the problem is that the steering column can get worn requiring new steering column OR a repair kit. Mine doesn't seem to need the column treatment, but defiantly needs the support brace and Tie rod assembly. Do yourself a favor and go to YouTube and search "Death Wobble" or "Death Wobble Repair." I learned a ton very quickly and more to the point, the right place to start looking, especially for those that say, "I've changed everything," this is a good place to start. Get the heavier rod assembly and steering gear brace. Good luck!!!
28 Mar 2015, 21:26
The “death wobble” (shimmy/oscillation) you’re referring to can happen on any vehicle. It’s typically a severe shimmy at the front wheels, triggered by harsh road contact at high speeds. When speed is reduced, the shimmy stops, until the same trigger point is again reached.

I’m sure you’re reading and watching all kinds of interesting stuff about the problem. But the smart thing to do, as techhelp2 suggested, is inspect and replace any worn steering and suspension parts before spending money on guesswork.

If the shocks are original, and one leaking, replace them. And in reality, only a qualified technician can do an accurate inspection of the front end. I've often seen owners miss obvious worn components simply because they’re not viewing and/or testing correctly.

The only tie rod related recall on your truck involved the left outer end fracturing and coming apart. You may be reading about upgrading to a newer model linkage setup. And the steering column is not typically a factor in this type of condition.

If ALL aspects of the front end are indeed tight; replace the shocks, get a wheel alignment, and let us know how you make out.

2008 Dodge Ram 1500 QC 4X4 5.7 Hemi has a slight vibration in either pedal (brake/gas) when accelerating and braking. The problem worsens at 2000-2500 rpms and 50 mph. I cannot hear any noises and can distinguish the vibrations from when my MDS kicks in. I know i have a bad passenger side CV axle gasket (on the differential). I also have a torn passenger side upper ball joint rubber housing, but i don't believe the ball joint is bad. I have rotated the tires and inspected every other suspension linkage, u joints, tires and from what i can see nothing is wrong. With limited knowledge of fixing my truck, could this be a bearing issue or a U joint? I should also state that when trying to replace the CV axle gasket the axle shaft would not release from the CV joint causing it to partially come out of the differential which i then had to bang back in to set it back in the beginning position. I do not want to venture into changing my entire front end if it is a simple problem as replacing a U-joint, wheel bearing, or rotating a drive axle. please assist.
31 Mar 2015, 18:39
RE: Brian, A bearing will give a grumbling or growling noise it won't give you a vibration like you are talking about.

You can not determine the condition of the universal joint by just looking at it. You have to remove the shaft from the vehicle and move it in all directions to see if it is binding or seized.

If you get the vibration in the brake I would check the run out of the rotors to see if the rotors need to be cut.

In some cases if the engine has a misfire in a cylinder usually caused by a bad spark plug or ignition wire. You would feel it when the engine is under a load, usually climbing up a slight hill or incline. This is usually found in the engine RPM range you are mentioning.

Hey guy I found the problems to the shake an vibration in the 09 10 11 dodge ram with tubler rear contral arms .... The bushings r bad it took it right out of my 09 dodge ram 1500 4x4 stl 5.7. Himi
16 Apr 2015, 20:02
my truck is doing the same thing kinda at 45 to 60 mph the truck jerks and shakes its lifted 2001 dodge ram 4x4 2500 what is this non sence helppppppp
17 Apr 2015, 06:56
RE: CJ, You are going to have to get the truck on a rack and go over the entire truck from front to back. Check the front end parts like the ball joints, idler arm, pitman arm, center link, tie rods inner and outer, upper and lower control arm bushings, stabilizer links and bushings.

For the rear there is a recall you should look into like:

966: The rear axle spring clamp bolts on about 2,700 of the above trucks may loosen due to a bent spring seat. This could cause the axle spring clamp bolts to slip off the spring seat or break, which could cause an accident without warning. This may have been fixed when the truck was new but you can go to the dealer and they can run your VIN number to see if your truck qualifies for this. There are others that are related to the Quad cab trucks, the dealer can also check this out by your VIN number.

Also check the leaf springs for worn bushings, stabilizer bar and bushings and links (if equipped) and for broken bolts, bent spring seat and broken leafs in the spring.

Check the universal joints for front (4 wheel drive) and or rear shaft for being worn or seized. The shaft needs to be removed and inspected to confirm a worn universal joint.

You mentioned that the truck is lifted; check the drive shaft angle. Too much angle can cause a vibration. Too much run out of the shaft (bend in shaft) can cause a vibration.

All shocks should be inspected and replaced if needed. Also check wheel balance, tire condition (bubble in tire or inside belt torn away) can cause a vibration and rims should be checked to make sure they are not out of round (bent).

Hi I have a 2009 ram 1500 hemi 4x4 drove smooth till I had a flat now have had tires balanced 12 times still shaking steering wheel and seats. Dealer also did a seal on t case same day as tires. Been to dealer so many times getting frustrated they just tell me tires need replaced these are new tires!!! Nitto terra grappler 295/60/20 they say to aggressive tread. If that was the case it would have did this from day one. Please help
22 Apr 2015, 15:24
RE: Brandy, If there was no vibration after the tires were installed and the seal replaced then I would suspect the tire that went flat or maybe even the rim. Try this, rotate the tires put the front to the rear and the rear to the front and see if the vibration changes. If it does change then suspect one of the tires that previously was in the front before the rotation. Also have the front end inspected for any loose or possible bent parts. Check those tires on a wheel balance machine for excessive run out (bend or warp in rim). You should find another shop that has a wheel balancing machine that can check a condition called wheel force variation as well as tire and wheel run out.
22 Apr 2015, 16:59
Tech help 2 : have done all those been to four different shops from two dodge dealers to a tire shop and regular mechanic all have road force balanced checked rim even spun tire in the rim. Still no change. 60 mph seats and steering wheel shaking crazy thing is at 62 goes away then comes right back. Checked all front parts. Don't know what to do really don't want to have to buy new $1000 worth of tires. Them 20s get expensive. But I will NOT get Nitto Terra Grapplers for sure
23 Apr 2015, 16:40
RE: Brandy,

Did anyone check the drive shaft for a bad universal joint?

If all of the things I listed were checked then this is the next step. The drive shaft should be removed and have the universal joints inspected, have the balance checked and also the run out of the shaft (check to see if it is bent). The drive shaft angle should also be inspected to see if the angle is excessive and out of factory specs.

You can try to remove the drive shaft and replace it 180 degrees from the previous position, sometimes changing the position can make the vibration decrease.

i have a 1994 doge ram 1500 dixie custom that shakes the dash board like an earth quake when the truck reaches speed of 45 - 60 . the mechanic installed a damper thought that would fix the problem now he is not know. can you shed some light?
29 Apr 2015, 12:37
RE: Julie, Check all of the components of the front end like the ball joints, tie rod ends (inner and outer), center link, idler arm, pitman arm, upper and lower control arm bushings for any ware or excessive play.

Check the balance of all four wheels.

Check the universal joints by removing the driveshaft and inspect the universal joints making sure one or both are not seized.

I have a 2012 GMC sierra 1500 with a 7.5" RCX lift. Recently, my rear end started to sort of fishtail back and forth any time I hit a rough area on roads, and it's really hard to even keep control of my truck until the road smooths out. I have brought it to a shop and they could not find anything wrong. I have gotten my tires balanced and made sure they have the right air pressure. I checked the pin in my blocks to make sure there wasn't any play for them to move around. I checked to make sure nothing on my suspension is loose or worn. When I jacked the rear end up, the only thing I noticed was that I'm able to move the leaf springs side to side with a crowbar fairly easy. Is this because the leaf spring bushings need to be replaced? And could this be the cause of my rear end going crazy on rough terrain?
05 May 2015, 10:11
RE: Michaela, The leaf spring should not move at all. Picture the truck going over the bumps; the truck goes one way and the rear end is going the other. This is causing the fish tailing and not being able to control the truck on rough terrain.

Have the leaf springs and mounts inspected and replace any part that is worn or defective. The company that did the lift should inspect their work and repair as needed.
05 May 2015, 10:32
RE: John Lara, If you have a vibration in the gas pedal then it is possible that something in the engine compartment is touching the body that could be transmitting the vibration to the gas pedal.

The truck should be put in the air and inspected underneath and above inside the engine compartment for anything out of place near the mounting area of the gas pedal that may be touching like any pipes, hoses, cables or wire harnesses. The vibration could be transmitted through these items to the gas pedal which is why you are feeling it when you drive.

Test driving a 06 2500 dodge ram, my cousin hit the gas pedal hard for some reason, and now we have 2 vibrations- one is noticeable all the time and seems to originate from behind and comes up thru the seat. The other is only when moving forward from complete stop, and feels like a type of slippage in the rear tires. Could the two types of vibartion be connected and possibly the result of hitting the pedal extremely hard when we test drove it ; didn't seem to have any vibration before cousin floored it. Maybe the hemi engine is so torquey it twisted something in the drive train,or damaged some splines where the driveshaft connects to transfer case? Thanks for any thoughts, Chris
15 May 2015, 06:45
Hey Chris,

Stomping on the gas isn't going to damage anything that wasn't about to break in the first place.

Your description of the vibration(s) is kinda tough to diagnose from here, but if it is significant, spend the diag fee at a Dodge service department. They'll tell you what the problem is, give an estimate, and go over the whole truck.
10 Jun 2015, 10:57
2006 Dodge Ram 2500 Cummins Diesel. 6 Speed Manual Transmission. Severe Vibration when the truck is decelerating. I've had the tires re-balanced, 6 of my weights were out of place. I have off road 35's. I've replaced both hub assembly's Brakes and Rotors all around, U-joints, and also replaced the e-brake pads (which I know wasn't causing the issue but it was needed.) Still when I drive it and the RPM's begin to go down it's a horrible shake and vibration. I don't know what to do, my tie rods are fine. HELP! I'm about to set it on fire!
15 Jun 2015, 09:57
RE: David,

The only thing I can think of is the drive line angles change on deceleration.

First check the transmission mounts and engine mounts to make sure the engine and transmission are not shifting position when decelerating. Also check the bushing and control arms on the rear end and or front differential (four wheel drive).

If the mounts are bad this can change the angle of the drive line causing too much of an angle to the universal joints causing this vibration.

Check this out you checked out everything else, it's worth a shot.

I have really good treads on them. They told me no more then i drive it the tires should last me another 4 years. please help me under stand why this is happening
19 Jun 2015, 17:11
Re: Kathy Ramage,

There are so many areas to check for this problem it actually depends on the expertise of the mechanic.

The front end consists of upper and lower control bushings; tie rod ends on both sides of steering, center link, pitman arm, idler arm, ball joints (you mentioned). These worn parts can cause a vibration.

If the universal joints on the drive shafts are frozen with corrosion and rust the joint can't pivot and this can cause a vibration that will get stronger when you go faster. You just can't look at a universal joint and say it is good or bad; you need to take the drive shafts out of the truck and physically take the drive shafts apart and inspect the bearing caps. There is also a center bearing between the drive shafts (on two piece drive shafts) that would also need to be inspected.

I read on some forums that the U bolts on the leaf springs need to be re-torqued (tightened) because the shifting of the differential in the rear (front also if 4 wheel drive) that sit on the leaf springs can change the drive shaft angles which can contribute to the vibration.

Worn engine mounts and transmission mounts can contribute to a vibration. If the transmission or engine don' t sit in their proper position it can change the drive shaft angles, if the angle is excessive it can cause a vibration.

Letting the truck sit for a long time like you said can put flat spots in the tires which can cause a vibration. If you drive the truck for awhile it usually goes away. There is actually a service bulletin on this condition.

These are some tips to pay attention to which can help you solve the vibration problem.

Hi, I have a 2001 Dodge Ram 1500. When I get to around 40-50 mph and I try to mildly accelerate I get a bad shake in the truck and I think it is coming from the back right passenger tire. If I heavily accelerate through the 40-50 mph mark it doesn't have that shake. What should I look at on the vehicle to hopefully diagnose the problem? Its a used truck I just bought with 150k miles on it.
19 Jul 2015, 09:28
You would first need to check out the balance of the tires. Check the rear leaf spring U bolts and spacers for proper alignment and torque of the U bolt nuts. Check the universal joints to see if they are seized, you need to remove the drive shaft and inspect the joints. The last would be to have a mechanic check the proper operation of the lock up torque converter. You may be feeling the converter shudder under light acceleration.

I have a 1998 Ram 2500 that intermittently feels like I'm rolling on rumble strips when braking.

What suggestions do you have for me to do?
Seth Heth
07 Aug 2015, 20:12
***Problem Solved*** I have discovered the source of the vibrations I was feeling. The fact that it was happening at certain speeds had misled me to believe that the vibration was coming from my rear (Thinking that the acceleration was a factor seeing how i felt it when it was accelerating and was not happening when i was let off the gas peddle. ) I did a full tune up and upon inspection of my spark plugs, along with codes popping up saying that I had a misfire in cylinders #5 and #7, they were very burnt and had probably not been changed from the previous owner in quite a long time. I had replaced the spark plugs and I noticed that the vibrations had left. It must have been misfiring so badly that it messed with the harmonic balance of the engine its self and probably had an issue also with the timing. I just wanted to post this to inform people that sometimes a huge problem can be a small problem. No shop I had taken it to, or my car buddy experts, could pinpoint the problem. And we all had agreed that it was a very odd and unusual problem and none of us in a million years would have guessed that a misfire would vibrate the vehicle so badly. Thank you Techhelp2 for your timely response and your willingness to give advice to people. I appreciate it alot.

I have the check engine light on sometimes its steady, and sometimes its blinking. some online posts say it could be related to misfire, sparkplugs or the MDS system? anyone have this sissue with a similar model and found out what the issue was? it would be a great help.
07 Nov 2015, 13:52

Check the u-joints in both drive shafts.
07 Nov 2015, 13:55
Certainly sounds like a misfire. Gotta check the DTC(s) which may narrow down the problem cylinder. Then diagnose the cause; spark, fuel, or compression.
10 Nov 2015, 12:16
I have a 2006 automatic Dodge Ram 2500 HD, with a vibration in the rear. Had u-joints changed and back tires are balanced. Vibration happens at 60mph. Mechanic added oil to transfer case, not drained. Still have vibration. Where should I look next?
10 Nov 2015, 12:59
RE: Marci, There are a few possibilities; the drive shaft could be out of balance, an axel could be bent, you may have worn rear end mounting parts like control arms, spring U bolts loose.

When the vibration happens put the truck in neutral, if the vibration goes away it is in the drive line. If it still occurs then it would be related to tires and axles.

You can also try to turn the drive shaft 180 degrees from its original position and see if the vibration changes.

I have a 1999 dodge ram sport 90k miles 4x4 5.2 auto trans np231d t case. I left the store to head home and noticed a severe vibration once i hit 20mph i actually pulled over thinking i had a flat tire but all was fine i made it home about a mile drive severe shake the whole way like i had a square tire. I jacked it up and checked the u joints all good and tight i started it and ran it with the wheels off the ground and used a stethoscope to listen and heard nothing from the rear end or t case but you can see the drive shaft bouncing at the output shaft i pulled the housing off and checked the output bearing and it looked fine i shook the the shaft with both hands and there was no play I can't figure out what the issue is and the truck is not drive-able because of the shake it feels like something is going to break it has never done this before and came out of nowhere i didnt hit any bumps or anything I dont want to start replacing stuff if i dont have too but i have no idea what it could be the truck runs great no issues no check engine lights and the trans and motor mounts all look good. I would appreciate any advice.

Also the shaking gets worse the faster you go and is constant it does not change when it shifts or when i let off the gas at 15-20mph you can feel it start and at 40mph it feels like i have square tires you can't go much faster than 40 without something breaking I figured if it was a bad bearing or gear in the t case or trans id be able to clearly hear it with my stethoscope but like i said everything is quiet I thought it would have to be either a bad output or input bearing on the t case but you'd think I would be able to hear it if it was that far gone

RE: Charles B, Check the universal joints. Just looking at them is not enough you have to check the movement of the joint and also try to take off the bearing caps to see if there is any rusted, frozen or seized caps. You have to check all of the joints and center bearing if equipt with one.
