Its quite a severe wobble on the steering wheel. I replaced the steering damper as It was only 20 quid and thought it might help. The old one was completely shot, and the problem seems to have improved slightly but is still apparent. Anybody have any ideas as to what it may be? Thanks for any help. Tom.

(i only got 3000 miles out a set of cheap spurious discs,they're false economy,second set .. good quality set still perfect 8000 later) plus cheap pads cause warping as well.
