You can center the steering wheel by loosening the collar bolts on the drag link and slowly turn CW or CCW to determine if the steering wheel is moving the correct direction.
The question you should ask is.... Why is the steering wheel off center ?
Do you know if the steering box was centered (number of total turns of steering shaft divided by 2 to equal the half way point of turns) or turned the steering wheel from center during steering box installation?
This could clock your steering wheel off center and possibly damage the ribbon cable for transfer of electrical signals while cycling the steering wheel making turns driving your Jeep.
