[Biturbos4] Control arms

[David Pramanik]

If it is the typical control arm failure where the front end it clunking/rattling/groaning, then it is not an emergency at all.  The noises are very annoying but the safety of the car isn't compromised (I wouldn't necessarily do any track driving, but otherwise it's fine).
 
I would recommend doing all of the front control arms even if only the three you mentioned are presently faulty (the others won't be far behind).
 
There are no combined kits for the S4 control arms, but MANY S4 owners (myself included) just use the B5 A4 control arm kits as they are interchangeable (as long as you have the steel uprights, which all S4s except the early 2000s do).  The Febi-Bilstein control arm kit is a good option.  The one notable difference between the S4 and A4 parts are the tie-rod ends.  The A4 tie rod ends are rubber isolated (so softer), while the S4 tie rod ends are solid.  If you can either:
a) use the softer A4 tie rod ends
b) put the A4 tie rod ends from the kit on the shelf and buy S4 tie rod ends
c) leave your existing tie rod ends in place (if they aren't bad).
 
Hope that helps.
