stutch Posted February 4, 2002 Share Posted February 4, 2002 After replacing the 636 bushes on the rear of the front lower wishbones I noticed on reassembly that the central steel tube of the bush sits up against the upright of the chassis (Where the 0.5" UNF bolt goes through both). I was wondering whether anything was missing or if this was normal - does wear occur between these two faces? - greased both faces before assembly. The wishbones now operate smoothly but stiffly. I didn't build the car and I don't have any bits left over but that doesn't mean that additional parts were not installed in the first place. Any advice most welcome.

Peter Carmichael Posted February 4, 2002 Share Posted February 4, 2002 The central tube should not move relative to the chassis. There is no wear. The movement is all accommodated within the rubber of the bush. Link to comment Share on other sites More sharing options...
stutch Posted February 4, 2002 Author Share Posted February 4, 2002 So just to clarify, the central tube of the bush should be pulled up tight agaist the chassis via the clamping action of the bolt. And as you say the movement of the wishbone is induced through the movement of the central tube relative to the outer tube of the bush by the rubber stretching due to the rotation?

Graham Perry Posted February 5, 2002 Share Posted February 5, 2002 Stutch, Sounds correct. I have seen a couple of cars with a very thin shim or washer between them but it isnt strictlty necessary. Remember not to tighten the bolts until the car is back on all four wheels on the ground. If you tighten the bolts with the suspension dangling it will wear out the bushes in a very short time, as they will then be stretched beyond their elastic limit upon suspension compression.
