Turn steering wheel all the way in one direction. Turn it the completely the other way counting the turns as you go. Now center the box going back again 1/2 the amount of turns. This will be where the steering wheel needs to be put back on straight. Drive down the road to see where the steering wheel sits while driving straight, make some sort of reference. Turn drag link...lengthening...until steering wheel is where it is supposed to be. Test drive again
