I feel your pain.
First Audi I had had "torque steer". Stood on a persuader to loose the wheel bolts, the wheel rolled forward , said "Aha", looked under, saw the shot bushings, bought and replaced them. Royal PIA. Had to pop the balljoints to do it Then getting the balljoints back in, is another PIA, but easier than getting the sway bar in with them in place.
On the '90 100 I have now, same torque steer, had the bushings ( I "knew" what the problem was) and EVERY thing else replaced. Still got it, no freaking idea what the hell it is.
Good luck, pal.
Cheers,
George
