And elaborate I shall.
The noise is coming from the steering shaft assembly to the steering box. It wasn't significant enough to feel in the steering wheel (to me), but I heard it as I drive with the windows down. The noise was lessened a bit when we moved the grommeted hard line(on the steering box. If I remember correctly there are two or three hard lines coming off of it) a little bit to the left.
My best guess is that since he did the MML and BL without putting a spacer or steering brace in, it is binding up from the stress from wheeling and DD. I don't think that it's the joints itself, but maybe instead of a dead on input angle into the steering box a bad angle has been created by an impact when wheeling. Jeepinsoldier put the steering brace in with his MML and BL, so I'm sure he can elaborate. Either that or the hard lines were tweaked somehow.
As was said right off the bat, my best guess.
