So in that other recent long thread (out of all the long threads ad infinitum) did you fit and ditch those spherical bushes from Jamie Porter seadart? Always thought there was a potential problem with that solution.
No they were actually for a friends car, he thought he'd try the spherical bushes.. I gave him a hand.... as I'd already done a couple of poly bush jobs by then.. but TBH I personally preferred the powerflex.. although I didn't get to drive my friends car much.. I guess if it were a track car and I wanted ultimate performance I'd go for spherical.. but on the road with a clown like me driving it doesn't seem to make much difference.. I'd say that powerflex is more 'comfortable' than spherical after they have settled in.. my car was originally all spherical.. some of which were knackered.. with the exception of the springpan inners..which were rubber.. initially I just changed the rubber inners for powerflex.. it was still hard and crashy.. well I thought so.. so I powerflexed the lot.. including the upper arms.. and along with new shocks the car was transformed.. its done a lot of miles since then and apart from a small crack in the shock bush flange it's all as good as new,, no squeaks..
As far as I know the other car with the spherical bushes is still ok.. I think that was done about 18 months ago.. next time I see him I'll ask if we can swop cars to compare.. I can understand why people prefer to use original parts.. I do usually.. and I think Jamie Porter and crew are great guys.. I get most of my stuff from the Alfa Workshop because they never sell crap..
All this business about 'which cars had what' is a bit confusing as you never know who's been at it before you..
I heard that in the early days dealers were fed up with changing rubber bushes under guarantee so they fitted spherical.. regardless of the model.. another friend of mine had a car with rubber on one side and spherical on the other.. must have been a quick 'get it through an MOT using a second hand arm' job.. who knows??
So to sum up I'm very, very happy with my powerflex job.. I was a bit cynical to begin with being a bit of an engineering traditionalist and all (old git).. to tell the truth.. first time I saw polybushes.. I think in the late eighties I thought they looked like kids building bricks.. never thought they'd ever be taken seriously.. and a friend of mine who's the same age still won't be convinced.. (stubborn old git)
I did my suspension in this order with about a couple of weeks between each operation..
Springpan inners....shagged rubber.. changed to powerflex..
not much improvement.. but safe in the knowlege that my subframe would be ok..
Remainder of lower arms.. spherical.. some shagged/sticky/siezed.. changed to powerflex
got rid of most of the bangs and crashes and a better ride.. handling improved.. still some knocks..
Upper arms.. very shagged rubber.. changed to powerflex..
reduced knocks further.. corners a lot better.. just one annoying knock now.. low speed potholes etc..
KYB shocks.. all knocks gone.. totally knockless.. alignment checked.. it was ok.. tyre wear even.. job done..
