Hey there Scott,
Both mechs manhandles the axles. Gary said he unbolted the axles from
the flanges and wobbled, wiggled, and generally harassed them and
everything felt fine. No bindings, no loosenesses, nothing felt wrong.
Regarding rear wheel brg play, how can I check that? Where is the brg?
(I didn't even know these were still using brgs in the '80s.)
If tomorrow's weather is as sweet as today's I will check that muffler
question. It's possible, I can't say it's certain, but the noise MAY
have started after the van was crunched by the parked aircooled bus that
was totaled by the guy driving down our street. The tailpipe has a 3/4
moon cross-section from the collision, which suggests . . . merely hints
at . . . tempts me with the possibility that the muffer is banging the
body like *(=== similie redacted because this is a family show===)* in a
dirty video.
