I had to replace the top and bottom bearings in my tractor. It is manual steering. Problem is I can't get the front aheels timed.  The right wheel will go to extreme right and the left will barely pass center. The other way the right wheel will go to the extreme right and the left wheel 3/4 the way to the left. The worm was never taken off the shaft. The gear that operates the right wheel as one large tooth on the gear.

When I put it back together I counted the revs the steering wheel and put the worm about center. The large tooth gear would only line up with the rack teeth.

Question is what is the procedure for realigning the front wheels?

Thanks
