I have a '96 4x4 all stock and have had to do little repair to keep this thing going. I have noticed that the front suspension doesn't seem to be as solid as it once was....but nothing specific. Anyway, I'm planning on replacing some bushings to try and stop a chirp I get from the front end. What bushings are the first usually to wear out and need replacing? I've heard the control arm bushings can be troublesome to replace. It has 140k and the only replacement to the front suspension has been shocks. Any thoughts?
