Audi A4 Avant B6 2002 - Power Steering Issues - A3 A4

I'm not even sure I have a problem with my 70k Avant, but since replacing the Alternator drive pulley, the steering feels 'wooly' and vague to me.

It may well be the case that I'm just paranoid, but it seems that when going over a slight bump the steering seems to pull one way or the other, and I seem to be always correcting it. Checked the tyre pressures, topped up the fluid to no avail, the tyres are wearing slightly more on the outside, and you do hear a slight (grinding?) noise from the pump when turning the wheel lock to lock when parking, but that could have always been the case. It could be just that I've noticed it after suffering the noise the failed alternator pulley made.

interestingly my OH drives the vehicle probably more than me and has no problem with the car at all.

Any thoughts greatfully appreciated.

If bumps are affecting the steering I would have thought you either have a worn suspension joint or slightly bent suspension component.

You will need to jack up the front & check for play in all the joints & make sure nothing is bent.
