Steve,

The rod ends do wear, but they do so very slowly. In the last couple of years I have only had a request for 1 set of rod ends by a member of this board.

But the rod ends bearings like all bearings will wear out at some time.

If you are getting some noise in the back check to make sure your shock bolts are tight and that the upper nut and washer have not compressed the rubber shock bushing to the point where the large washer is hiting the bushing cup over bumps. It makes a rattling noise.

Also the rear subframe bushings if worn out will to the same thing.

Be sure to check the rear swaybar bolts and make sure they are tight too.
