I dont know if you have a manual transmission or automatic. If you have a manual, do you get any loud "clunking" noises followed by some back and forward swinging when you shift from gear to gear? or when you're stuck in some kind of traffic, and you put the car 1st to inch it forward, and disengage the clutch, does it give you a loud sound?. This happened to me when my subframe gave out. Sucks. it cost me $600 to repair.
