Torque thrust bushings in the front suspension may crack and leak oil, this causes steering alignment problems and excessive tire wear. Another symptom of a worn bushing is a clunk or thud noted when turning, on hard acceleration, or hard braking.

same problem as described: leaking fluid from the bushing. I'm about to go back to give the dealer a third try at repair on his nickle.
