Sounds like a great shop!
Your theory about the cap backing out makes the most sense. The trunion looks fine and I would hope the casting on the double cardan wasn't junk. Probably too much damage on the parts to do any kind of decent failure analysis or look for porosity. Given your track record with caps coming out, that's probably the most likely scenario.
