I went the Poly route last year after finding that the rubber mounts were
completely knackered and the bracket on one side cracked. I had read that when
the rubber bushes deteriorate it allows the whole shebang to move up and down
and that hammering effect contributes to the other problems in the nether
region. So I boxed in the brackets, ground out and welded up the crack and
fitted poly bushes. I just checked them last week and no obvious problems and
no issues with noise or vibration that I would notice.

Subject: [net] Differential mount bushes - rubber or poly?
HI,
Dropping the differential for rebuilding and I was wondering what people liked
for replacing the differential mounting bushes - rubber or polyurethane. This
is part of a total rebuild of the car, and I'm trying to find a way to improve
the handling without making the ride too harsh for daily driving. I'm leaning
towards rubber for vibration isolation but am curious what others have done.
Thanks!
