Moose it could be anything...
But I would really have to drive it, and look it over...
Could be clutch chatter
Could be the T-case slapping the belly pan (if it was that bent)
Could be tires,
Could be U-joints
Could be front d-shaft
Could be F-Tcase output bearing.
Could be the exhaust hitting something...
The list goes on... however most of those things dont fit the slight info you are giving us, (vibe and noise) but you can still get the idea....
Until we really take a look, I cant really say.. (sort of vague) if I get free at the Rally, and Pete has not solved it, I will take a looky for yaa...
