I had a difficult time pressing in some polyurethane bushings I made for my
83 Coupe. The poly would expand above the hole and not move. I was at the
point where the A-arm was going to bend if I pulled much harder on the arbor
Then I decided to follow Murphy's 14th law of auto-repair and whacked it
with a big hammer :-) and it went in with about 10 hits. (soft faced hammer
I don't know if this will work with rubber bushings, I've never tried it.
I've heard that you can burn out the old rubber with a propane torch but
I've been wary of hardening the steel, any metalurgists care to comment?
My method of removing bushings involves a drill press and is kind of scary.
gotta put the toys away soon:-(
PS, the last autocross of the season in Ottawa is this Sunday, we could
clean up if it snows. E-mail me direct for more info.
