Even though the Jeep XJ steering shaft install went well, it didn't make much difference in my steering looseness. I just misdiagnosed the problem. Even after the shaft swap I still had about 40-50 degrees of play in my steering wheel before the truck would start to turn. It was enough that I haven't wanted to drive the truck very far. All of the steering rod and tie rod ends seemed to be tight. No one else was around so I started the truck and turned the steering wheel through the wing window and the dang steering box was still moving quite a bit on the frame. I had tightened this up after I first bough the truck and it helped, but didn't cure it. After the steering box was removed from the frame, you can see how the bolt holes were ovalized. I decided to buy a weld in frame repair kit and the bolt in steering box brace from ORD:

Welding in difficult locations and bolting through tight holes in the ORD brace, frame, weld in plate, and the steering box.... It took much longer than I thought it would. The white paint on the frame is weld through primer. I figured I didn't want the frame and plates to be uncoated where they aren't welded. I did have to take a little bit of metal off the front of the weld in plate because it interfered with the bumper bracket. Oh yeah, I took the bumper off and it made working under the truck alot easier. The brace comes with bolts but you need to buy longer bolts if you use the weld in plate. Lowes has the grade 8 bolts, nuts, etc. I used three 7/16-14 x 3.5" bolts and one 7/16-14 x 2"??? bolt. I also loctited the bolts and used nuts on the outside of the steering box. After it was all welded I sprayed it black.
