Hi Colin, Undo the clamp that holds the drag link to the track rod after you have the wheels set in the straight ahead posiiton. If the drag link won't slide up and down the track rod easily you may have to take the track rod end off the drop arm. By turning the steering wheel to the limit left and right whilst detached from the wheels, count the number of turns and halve it to get the sraight ahead for the box. Then re attach drag link to track rod and you should have an equal amount of turn both ways. You should also check position of drop arm on the steering box splines when the box is in the straight ahead, so that it scribes an equal arc to either side of the center position. Hope that's clear! Cheers.
