I confess, I resisted Ron's suggestion that bad radius arms were causing=
=20
clunking.  But this morning as we headed out shopping, I said to my=20
wife, "This is what Ron says I should check.?  When I touched it, it=20
moved!  So I wiggled it, and it was not the bushing that was bad, the=20
arm had fallen completely off the bushing and it was rattling around on=20
the bolt with no bushing at all.  I haven't a clue how there was enough=20
room in there for that to happen.

So much for my judgment.  Ordered new arms.
