hmmm... check the other side. make sure the ebrake is loosen when you are correcting this, or else you'll have one hell of a time. That was what i ws feeling when i frist got my car. the tire only locked one side (drivers) cuz it was the only one connected. make sure both sides are connected, then look around the driveshaft area. Don't bash my drawing, you peehole!
Make sure those cylinderical nubs are in the sockets. its kinda hard doing it whn you can't get good light down there, but that should help. Hit me up on AIM if you need a quick response.
