everytime i make a right or ajust bear right my car makes a rattling noise on the left side. the rattling noise is getting worse and worse everyday. i sent the car to a mechanic, he checked it on the lift and could not locate any problems. he stated that he couldnt find anything, but i should start by changing my front shocks. before i spend 2000k changing every single part, can someone tell me if this is something that has happened to someone esle and the soltion? thanks for your help.
