I have worn out the bushing's in three different rear track bars in the last 6 months. I have owned the car for about 6 months and I know the rear end has been hit before. Could it be possible that the frame is bent and causing the bushings to flex and wear out? What else might be causing it?

 

I assume you have the stock rubber panhard rod?

If you have poly, then that is the problem, there are reasons that OEM doesn't use it.

With stock rubber, you need to lift the axle to ride height before tightening down the panhard rod. If you are installing on a lift with the axle hanging down that wil bind and over stress the rubber when it winds up to reach ride height.

I am using stock style bars with the stock bushings. Maybe that is my problem, I will try it.
