Steering box adjustment

The way I do it is loosen the pitman adjustment way up, the nut and screw on top so there is a lot of play in the steering wheel. Then loosen the big nut on the input shaft coming from the steering wheel. tighten that till it feels a little stiff that way there is no play in the worm screw. Tighten it up turn it to make sure there is no binding. Then tighten the pitman shaft up (make sure it is centered) till there is very little play and drive it if it doesn't center it self loosen it up a little.
