Failed a WOF for a noisy steering rack - it sounds like something is binding and releasing (sounds almost like a slow creaking noise) as you turn the wheel. No leaks that I know of. 1996 S6 sedan.

 Does anyone know of anyone who might be able to rebuild these things?

There is a rack available ex Audi tradition but is is an earlier non-servotronic rack AND it has the earlier smaller passenger side mount bolt (M8 vs later M10). I'm not that fussed about lack of servotronic but with the different mount bolt I guess I might be able to drill it out but don't really want to order it and then find out it's not really feasible). The rack in my car is 4A2422065AK.  Cheers
