Reason being is that the quality U-bolts have a rolled thread and the nuts distort the threads some as they are torqued down

Will do on the steering box check, thanks for the suggestion. I did look over my frame rivets pretty good and didn't see any indication of a loose rivet. Not sure what to do next, thinking about putting a little video camera under the truck and seeing if recording the undercarriage when the noise happens reveals anything.
