I have a 2000 S4, which I bought 6 months ago... It's been a great car thus far and I just replaced the drivers side rear wheel bearing two days ago and now there's a very noticeable "squeeeeek" when I get in the car, turn or go over uneven terrain. It sounds like an old pick-ups suspension. The only thing that I can think that might be making the noise is the upper control arm bushing... Also there is a barely noticeable knock from the same wheel that I can hear when starting and stopping. I'm thinking that this noise is caused from the tie rod. If anyone has any suggestions I would appreciate it!

 

I don't know if you DIY the wheel bearing or took it to a shop, but since you just replaced it have you checked to see that everything was tightened back together properly?

 

Could easily be the swaybar endlink.

 

Thanks Devil... it was the swaybar end link.

 

You're welcome - glad it was an easy fix
