Excessive torque is a sign of a broken motor mount, especially in front-wheel drive vehicles. When the mounts snap, the engine may move in such a way that it interferes with the throttle or gear shift. This can lead to leaks in the exhaust. This usually happens in the area where the manifold joins the main exhaust pipe, or the pipe may collapse. If the broken mount happens to be an end-mount (at the end of the chassis, transmission or engine), this can also lead to torque steer as the engine's power pulls the steering wheel in one direction or the other. Please post back your findings. HTH

If the rear toque boxes are in the correct place, and the axle pads are centered on the tie bolts, it is centered.

Forgive me. Don't understand (a dumb engineer) how a bad/broken engine mount can make a rear wheel drive car pull! Vibrate yes. Front wheel drive yes.

I think it has to do with the mass of the engine moving in the front of the car

A good 4 wheel alignment will show your thrust angle, which will indicate the alignment of your rear end. It isn't adjustable, as 22GT infers. About the only thing that should make it be wrong, if those items are correctly placed and centered, would be a prior accident having moved the rear and its mounting points.

I felt that if you read the explanation carefully, it would become clear, however, it's not nessassary to understand. Have someone put the car in drive and then reverse, rev the engine while you watch outside. Be careful!! If the brake doesn't hold, you could be injured or killed. The mount is supposed to move but if the engine jumps up everytime you put it in gear more it's more than likely that you have a broken mount. If you have any doubt, watch another similar car if possible, but they all move.

What about rear spring bushings If they are worn out the axle will shift and could cause the pull.

The eye bushings? I suppose so, but I've never seen one go bad. There's always a first time, I guess.
