Next up I needed to turn the ID. I made a bushing that has the same bore size as the steering box. This allowed me to press in the bushing and size it to the required bore for the .002" clearance.

Pressed in the new bushings and a new seal.

Re-assembly of the ballscrew. The ballscrew and bearing surfaces looked very good. I had previously bought another steering box to rebuild in the meanwhile, but the ballscrew and bearing surfaces had extensive pitting. At least it came with a good pitman arm to use.

Steering box assembled and filled with the class 0 EP grease as per the manual. Made my own gasket to use.

Here is the final product. I set the axial clearance of the ballscrew and the gearing. A new seal for the steering shaft was installed as well. Most of the slop is gone, but there is still a little bit present.
Much better than what it was. You can tell that the new bushings have an effect on the clearances because the slop has been removed from the center position, which is a positive (usually most slop is in the middle). When the surfaces break in again I may be able to tighten up the gear a little bit more to remove the rest of the slop.

The steering box has been coated in a rust preservative to prevent further corrosion and retain the bare cast iron look.
