I've got ~9,000 miles on mine. Mostly street miles.

I need to replace the uppers and tie rod ends.

I think the strut rods are ok. When I unloaded the suspension to check bumpsteer I did my best to look at them really close and carefully feel them while someone else tugged and pushed on them. The tie rods and uppers are obviously loose.

The heims make for smooth repeatable suspension movement. We used to have to run bushings in our circle track car. They were very temperamental on binding/snagging/resistance when we digital scaled the car. If you over tightened them sometimes you wouldn't get the same static frame (ride) heights. And that completely screws up chassis setup on scale when you setting weight balances to the nearest half percent or smaller increment.

The poly and rubber stut rod bushing makes the strut rod into a diving spring board.
