Well, you may or may not have worn parts, duz the car want to drift depending on the crown of the road or show other signs of slop? Presuming the alingment is really ok and the steering wheel is misalinged, you just need to tweek the tie rod ends.

You want to back out one side and move the other side in the same amount. This will hold the alingment but alter where the rack centers which also will center the wheel. Try backing one side out a turn and running the other side in the same amount. The steering wheel alignment will either get better or worse. If better, keep going until the wheel centers. If worse, you need to go the other way.

Good luck.
