[TheForge] Trailer bushings

[Chuck Robinson]

Hey Folks,
I was hauling a couple of tons of steel down I-10 on an old tandem wheel
trailer, enroute to New Orleans about a week ago in a heavy down pour.

After reaching my destination, I discovered that one of the trailer wheels
was gone. Since I was on auto pilot (probably taking a snooze) I never felt
the wheel go AWOL

After removing the bad axel I discovered that most of the linkage had to be
replaced.
I know sources for everything needed except for the plastic inserts in the
spring eyes and wish-bone links.
Does any body know what the inserts are made of, and a source for it?
Chuck
