Transaxle noise

Hey guys. About 3 hours ago I was involved in a hit and run and an uninsured driver hit me in the front wheels. my car is now overheating above 40mph, wont go above 60-65, and its making a grinding/scratching noise Somewhere near the passenger side, and the wheel isn't rubbing. It's a 94 Eagle Talon if that helps. Any ideas what could be wrong? I need some leads for my mechanic...
