at the track tonight and im pulling into the staging lanes and all of the sudden this nasty noise like grinding/screeching comes from the front of the car when i turn my wheel. so i stop and hit the brakes and it does it when i hit the brakes too. im wondering if anyone has had this problem and if its my rack and pinion or if its my brake/power steering booster? i really dont wana pay a shop $100 bucks to diagnose but i also dont wana throw parts at it and end up paying more for parts i dont need. please help me if anybody knows!
