Seized rear trunnions check, Vitesse Mk1 2 Litre

Hi. If when the rear end is jacked up, the suspension/wheels droop, would this imply the trunnions are not seized?.

Thanks

I cant see how the rear trunnions could ever seize Dave. In the drawing the steel sleeve 29 is longer than the plastic bushes 27 once theyre installed in the housing so it gets clamped between the uprights leaving the bushes free to rotate. Even if this wasnt the case and the bushes ended up slightly wider their plastic would soon be squashed as you tightened the bolt and then rapidly free off as soon as you started driving.  Maybe youre thinking of the sleeve seizing on the bolt which is very likely making dismantling difficult but not actually affecting the suspension movement....

Thanks Johny. I did wonder that myself, though I thought I had read this can happen? and can show as as a car having very negative camber. though I would have assumed this would be a worn spring etc?

I think the suspension joints that should be tightened in the correct position are more likely to be the spring eye bolts and tie bars as these dont pivot but just rely on their rubber bushes twisting...
