Have you tried tightening the steering box?

Locate the allen bolt and locknut on top of the steering box. It’s close to the radiator. The locknut should be a 5/8".

Mark the allen bolt so you’re oriented and know where the start point is, then loosen the locknut.

Turn the allen bolt clockwise a quarter turn to tighten the gear mesh. Tighten the locknut and road test your vehicle.

Be careful not to over-tighten the allen bolt. If you do, the steering may become too tight and get extremely stiff during a tight turn, possibly causing you to drive off the roadway.

Keep repeating the sequence, turning the allen bolt a ¼ turn at a time, followed by a test drive, until you're satisfied with the performance. If you over-tighten the allen bolt, turn the allen bolt back a quarter turn, counter-clockwise.

There is a risk of over tightening the box and causing it to wear out prematurely, so I suggest you tighten it to the point where the slop is gone, and no further.

From what I’ve read on the forums, most people will turn the allen bolt three-quarters of a rotation to one and one half rotations before they’re happy with the results.

This has cured a lot of slop in many Ford rigs.
