I bought a new car, took it to the dealer with less than 100 miles on it, and got the car back with the steering wheel off center. Someone hit something. They let me look under the car, and at the initial alignment readings. Thrust angle is zero, and I didn't see any visible damage. But both front wheels were pointed right with the wheel centered, and the total toe was close to specs. I am assuming that the rack is damaged, but I cannot remember any conclusive test for it. I didn't see the toe on turns reading, and I'm not sure if that reading will answer my question. I also assume that the turning radius will be different between right and left turns, but I don't have a good way to measure that either. Any suggestions on proving that the cause is the steering rack? As a note, the steering wheel was not that far off. The toe on each side was about 2 degrees off - one in and one out.
Finally, would you worry about this, or just shrug it off if the dealer refuses to replace the rack? They are replacing the wheel, and they did the alignment, but I cannot prove that it happened there.
