Randy:

I have almost 1000 hours on my 235 nose strut and have a
tolerable amount of wear. I don't think bushinging the
hole in the aluminum arm will make much difference,
as the bearing surface between the bolt and welded tabs
is much smaller area and therefore higher stress.

Either a fully-clamped rod-end bearing or the clamped
sleeve will eliminate the wear in the steel tabs. Those
designs will require that the ball end or clamped sleeve
(plus washers or spacers) be a smooth fit between the tabs.
Bending the tabs by tightening the bolt might lead to
cracking of the tab weld, possibly with loss of pressure
and fluid in the strut.

Anyway, the wear rate on mine seems tolerable - maybe
0.010 - 0.015" wear now. Looks like it will be another
1000 hours before I have to do anything about it. Most
likely the strut will need rebuilding by then anyway,
and I can figure out what to do then.
