If the steering wheel is off, but the car tracks straight, then the alignment isn't truely correct. There should be a centering pin the alignment tech uses to ensure the wheel is straight when the alignment is done. The wheel can only be moved something like one spline in either direction, anything more will effect the turn signal operation, plus shifting the wheel on the shaft is not the way to correct the alignment.
