My 1999 Grand Cherokee Laredo has a shaking in front end and thru steering wheel at 45 mph. I have raised vehicle and felt for play and loose components but have found nothing. Any suggestions?
Most of the time -- not all -- but most of the time the problem is a bent wheel (and/or hub), or bad or out-of-balance tire.
Jack up the front-end and spin the wheels manually while looking for a bent wheel or a wavy/chopped up tire. Then rotate the tires and see if the problem goes away. The rotation typically proves if it's a front wheel problem, or not.
Still got the shimmy felt in the steering wheel? Drive the vehicle to a speed where the problem is the worst, then let off the gas (or put the transmission in neutral) and see if the shimmy stops. If it does -- and you got a 4x4 -- it's most likely a bad axle.
Let us know how you make out following our suggestions.
your suggestion helped putting in neutral at speed it had problems it did not shake anymore, to replace they list with or without vari-lock axles what is the best way to determine this without pulling axles
The parts house will probably ask you for an axle code. The code will be either on the axle itself or ask the parts manager for the option code. The option codes are usually a sticker in the glove box or near the area where the tire jack is.
They may even be able to tell you which axle you have by the VIN number.
