Revisited the front drive shaft yesterday and removed it. Drive home was vibe free. I still detect a faint rumble not felt in the wheel/seat/floor like I did pre-ds removal, but I think I'll attribute this to the TT and the drive train being closer to the tub. I'm going to drive it for a few days to be sure then move forward.
I know some spots in MNF if you want to dump your vibrajeep
