Vibes at speed

[jay79cj7]

I've got a stock 00 XJ. I noticed today for the first time that I am getting vibrations through the steering wheel when I hit around 50 mph. The wheel was actually shaking quite a bit on the way to work, but not as bad on the way home. I have not done anything to it lately. The tires are about a year old. I haven't taking it wheeling to damage anything (its my DD). It has around 90k miles on it. I checked to see if the balancing weight fell of a tire and they hadn't.

What are the likely culprits?

Worn out front track bar is the most likely. Have somebody crank the steering to full-lock while you watch both ends of the track bar. Have them bounce the steering wheel back and forth againsy full-lock and you may see movement in either end of the track bar.

2nd most likely culprit would be worn bushings in the control arms on the front axle. Inspect with a flashlight and screwdriver.

	Track bar A track bar is a component of a car suspension system that provides lateral location of the axle. While the purpose of the rear suspension of an automobile is to allow the wheels to move vertically with respect to the body, it is undesirable to allow them to move forward and backwards, or from side to side. It is this latter movement that the track bar is designed to prevent. It is a simple device, consisting of a rigid bar running sideways in the same plane as the rear axle, connecting one end of the axle to the car body or chassis on the opposite side of the vehicle. The bar is attached on either end with pivots that permit it to swivel upwards and downwards only, so that the axle is, in turn, allowed to move in the vertical plane only.

Thanks Bounty. What do you mean by this?
