Wow, thanks for the info that clarified alot. From what you said, I think my control arms are the only problem as of now. My steering seems fine (other than my alignment is really off). Its the my driver side wheel seems not want to stay on stright. It seems to camber out and in as I turn the wheel left to right. However, I think I am going to replace the tie rod ends as well if my mechanic suggests it. I also forgot to ask if s4 and a4 control arms are different. I ask because I saw a bid on ebay and they claimed that the s4 control arms are bolt on with the a4 and provide tighter handling. Don't know if it completely true and its almost another 100 over the a4 control arm kit. Any thoughts?

Thanks
