It has been some time since my last post, but I have good reason - believe me. There are things more important than our cars, that's for sure. However, the time I can spend in the shop is a good opportunity to meditate, relax, and unwind after dealing with so many people all day long and helping them with their problems. I have been known to crank up a good southern gospel music CD or even one my favorite sermons from a preacher of yesteryear and have at in the garage with all the work (er, fun).

After the cross member was welded up by my friend Mike, I decided to smooth it up a bit and paint it with 3 coats of Rustoleum. I like the semi-gloss sheen on the frame and will use that for the sub assemblies as well.
I finally got back in the shop last night after spending a few weeks with other priorities. First up was the steering gear box and the rebuild. I had all of the parts I needed. The worm gear on the shaft was a used unit I found, but it was very near pristine on the grooves and fit perfectly. The bearings were already in good shape so I cleaned and kept those. I ordered a new seal for the sector shaft that holds the pitman arm. I got it from fleabay for something like $4 shipped and the thing fit very, very well. It was a US brand name seal, but memory fails me at the moment to tell you which one.
When I got it all completed, I was scratching my head over an "extra" part that I did not recall. After a few minutes it dawned on me that the large washer was actually the keeper for the original rubber seal for the sector shaft. I had forgotten that the seal was actually two pieces, so that large washer was obviously not need because the new seal was now one piece. The shim pack was interesting to deal with. I looked at the original number and thickness of the shims that were installed originally and I tried to install new shims that were an exact match. After torqueing down the bolts I spun the steering shaft and thought it seemed loose. As a matter of fact it was so loose that it actually had a little but of runout (vertically).
"Well that can't be right," I muttered.
After I looked at it crosseyed for a moment... "Hey bonehead! The replacement worm gear - that's what making the difference here."
So I removed one of the original 3 shims and just checked to see what would happen if there were no shims.... TIGHT as it could be!
No wonder there is a little frustration over getting the pre-load right. I guess it is a little tricky. I went through my pack of shims and just kept working on it until I found 3 that didn't have any play on the runout vertically but still kept it spinning "right"... now, what "right" actually is, I have no way of knowing. Someone had suggested using Ford's shop manual for the load, but that is with the leverage of the steering wheel. And... I don't have a torque wrench that goes to a very small inch/pounds. I guess I need a spring scale anyway. However, I would like to get this right on the bench before install... any ideas?
I greased the gears up pretty good and wrapped it all in plastic until it is installed. I have gear oil for it 80w90.
While I was at it I decided to put together the drag link. It was already in good shape - it just needed to be cleaned up.
Things were going so well I decided to tempt fate and dismantle both upper control arms. I needed heat on one occasion but things went reasonably well. Again, some of the rubber was about ready to disintegrate so it was a no brainer to replace all of this stuff up front.
For those of you that really know your stuff.. yes there are 3 large washers per upper arm. The third is in the box.
