Okay here's my problem: Whenever I turn my steering wheel to the right while I'm sitting still or moving slowly (under 15mph) my car makes a creeking sound and will clank. I got under it the other day and the rack and pinion bushings looked bad worn. It looked like metal was grinding metal. Would this be causing the noises my car is making? If all I need to do is replace the bushings what all will I need (tools and parts) and can I do this by myself in my driveway? Thanks for any help!
