Just to add, I usually disconnect the drag link or center link from the pitman arm so that I can move the steering gears and feel for notches in the movement. If it feels notchy then there are spalled out areas on the worm gear. They ride most of their life in the straight ahead position so that's where a lot of the wear usually is. Once off the straight ahead position, there is more and more play to allow the wheels to steer properly in a turn. This is normal so the only place you can take any slack out is in the straight ahead position.
