I think he is referring to the pitman arm. If he has play in the steering box, then the pitman arm will wiggle back and forth a little. The thing to do for that is adjust the pre load in the box. On top of the box is a screw with a lock nut. Loosen the lock nut and tighten (clockwise) the screw to increase pre load. Only an 1/8 turn at a time, and no more, until the play is gone. Don't over do it. This worked for me.
