Replacing Rod Ends

Update by Per Schroeder to the LeGrand Mk 18 project car

The old rod ends were worn, and we could feel that several had some play in them. Not good for a suspension!

While the trailing arms were off the car, we stripped the paint from them and added a new coat.

After we had to replace a rod end at the Solo National Championships, we took a good long look at all of the rod ends in our LeGrand’s suspension. We decided to replace every single one—that was the only way we could ensure we’d have a solid foundation going into our 2011 racing season.

We chose an old favorite of ours, Aurora Bearing Company’s alloy-steel PTFE-lined rod ends, for most of the suspension joints. The car is mainly held together by the 3/8-inch versions, but there are several larger and smaller sizes. We counted 22 joints in the rear suspension alone.

Once we have the car back together, we’ll need to do a full alignment and “squaring” of the car.

This all looks good, BUT now there is nothing left on the car to blame if you don't clean-up at every event!

Mine has only 14 if you don't count the ones on the swaybar links, 18 if you do.

Sunspots, alien abduction, cranial-rectal inversion—there are plenty of things to put blame on.

My only concern with the PTFE lined units is that they might be more sensitive to dirt comtamination and therefore prone to have a failure in the PTFE lining, which could cause the joint to become sloppy.
