steering wheel suddenly out of alignment

[pcvst.tech]

One of our Club Car "Carry All" carts here was brought in by it's operator with the complaint of the steering wheel being upside down. this bothered him because he had to clip his work orders upside down on the steering wheel clipboard now. The issue is that the day before the wheel was in it's correct position. One of the carpenters had taken the cart without permission, and had done something to it. I looked at the tie rods, and rack/pinion set, and everything looks normal. My question is this, is it possible for the rack and pinion to skip a tooth somehow, like if the cart hit a curb hard enough to pull the rack past the last tooth, but then be able to reengage with the pinion, and act like nothing had happened? The cart has a lot of wear in general, but the steering is not sloppy. Anyone here seen something like this before?
