Listers,
a flame wrench, aka torch, also works wonders for unseating rubber mush. A
quick light until they burn, leave on driveway or otherwise (ask the wife if
you can burn rubber indoors <G>) and they will fall out on their own. This
is a trick taught to me by a mechanic to be used on trailing arm bushings
(TR6) where the central pin has separated from the metalastic rubber. The
flame from rubber fire will not harm the aluminum, but a direct assault from
a cutting torch will. (So, if you get REALLY pissed off and wanted new
stuff anyway...)
PS: urethane bushings will transmit more road "shock". This means they
are doing their job. If you have anything more than stock 155 /13's on your
spit, you can benefit from urethane. That said, I ran my GT6 on 185/60 13
BFG comp ta R1 race compound tires and boy did it hold the road. This type
of preformance DID chew up stock bushings in about 10 k miles. And, in 6
tech (Len Rechenberger), it is noed that Tr6's go through upper bushings in
10k miles ANYWAY.
Urethane is a "modern replacement".
