I also rebuilt the "inner" joint, the one with three roller bearings inside a housing. One of the three roller bearings had come off its post. The remaining two were captured as intended, so I'm not sure how this one got removed. Anyway, it would not easily slide back onto its post. It is an interference fit.
So, I baked the bearing in the oven at 250-degrees F for about an hour. Then I placed the bearing onto the post. It didn't drop right on as I was hoping, but I used a C-clamp to squeeze it into place.
After that, I just greased up the bearings, housing, and boot and sealed everything up! Installation was a breeze since a friend helped and the test drive was a success!
