Thanks,
It does have PAS and I have noticed it freaks out in big puddles, I'll get the belt replaced and see what effect that has, the shocks are fairly recent so should be ok,am hoping to upgrade the suspension soon so will eliminate that, mounts etc could be a different story, so i'll check them out.
I hope the steering racks ok.
The tyres are new Pirelli P6000's all round so can't be them. I reckon the PAS could be a cause,
thanks for the tips, all suggestions gratefully recieved.
