Most of the wear occurs between the nylon bush and the sleeve. The
nylon washers wear against the plate on the frame, and the end plate,
but usually not enough to matter.

It's clamped in place by the end plate and nyloc. The outer diameter of
the sleeve wears against the nylon, but the inner diameter should not
wear.

I used Nylatron (from BFE) for all my inner pivots at my last rebuild.
I'm not sure how well it will outlast the original nylon in the lower
pivots, but it sure should outlast the rubber in the upper pivots ! I
also added grease zerks for the lower pivots, with a small hole through
the bushing for the grease to go through. But, I'm not sure how
necessary, or even helpful, that is.
