Suspension mountings

[SJAM]

Hi guys,

Wishbone to Chassis mountings - how "stiff" should the wishbone movement be with nothing else attached (uprights/shocks/springs etc)

I think my mount bolts are over-tight (requires effort to move by hand)

Cheers,
Stuart.

Hi Stuart, are you talk rubber or poly bushing...Poly will rotate and rubber will need setting at ride height, with the rubber acting in tension to stop you rotating the wishbone and both can be as tight as a man can get them with a pair of spanners. I have never seen a torque setting written anywhere (although the 1/2 UNF thread settting should apply).

Hi Adrian - It's a mixture of both but mostly the rubber ones. I just heard that unloaded, the wishbones should move pretty freely (but without anything lateral) otherwise it may upset the performance of the springs and shocks (return rates not right etc....)???

I hear what you say....but I have never tried to bolt a car up in full droop, I have driven and released/re-bolted other peoples cars, so it does affect the handling/shocks feel etc. A cat on hot bricks feeling would be how I descibe it.

Just to tidy this thread up... I jacked the car up, loosened the suspension bolts, jacked up the wheels to normal ride height, then tightened them down.
The handling is now MUCH better!

Thanks Adrian.
