" Would you mind describing what condition
you found the bushing rubber in once you got
the old ones pressed out of the arms? How did
they look based on what you could see of the
rubber before you pressed them out. Thanks."
Before the control arm bushings were removed it
appeared that only the edges of the rubber had
aged and cracked but that below the surface they
might have been more intact and therefore maybe
they could have been left for a while longer.
The only strong sign of trouble with the control
arm bushings was the squeaking from the front
end when the control arm moved.
More than anything I just wanted to go through
everything in the suspension, steering and brakes
so that I would have confidence that no trip was out
of reach of this GMC.
Other than the inspections I have made (or have
had made on my behalf) I have no indication of
previous maintainance etc.
Once dismantled the lower control arm that was
squeaking was found the be the one with the
seriously worn control arm bushing. I think
if it would have had a more serious inspection prior
to dismantling the problem might have been found.
The inspeciton was brief however because I felt
there was little point in spending too much time
inspecting parts I had already decided to replace.
I was surprised though that that one control arm bushing
was so badly worn when the coach only has 80,000 miles
on it. I feel confident that the miles are real since the ball
joints were original.
I guess I will have to chalk it up to age. 26 years is a long
time for rubber parts.
Hope this helps.
