I have a 1988 Iroc-z28 with a 305 TPI 5 speed. I'm having a problem with my car when i brake and make left turns. There is a Rubbing sound that my car makes. Seems like its coming from around the left front tire. The sound doesn't happen when i make right turns. Had it checked out by some people and they have no clue what it could be. They checked ball joints, calipers, mounts of the engine and transmition. Any clue what is going on here?
