I've got a 1990 S2 and when i get to about 65mph i get a wobble coming through the steering column and wheel.

The wheels are balanced and the steering rack and track rod ends in good condition.

I've think i remember reading somewhere that there it a plastic bush somewhere on the steering column that wears and can cause this wobble, is this true?

Any help or advice would be greatly appreciated as i like to get it sorted before i start using the car again.

Cheers, Mark
