Vibration in 4x4?

[Rammstein1224]

Hey guys i think this is somewhat normal but when i was on the interstate today i had it in 4x4 because it was really snowy today and when i let off the gas it has a loud vibration coming from down below and i cant figure out where but i thought you guys would know, its only when i shifted into 4x4. it didnt do it with the just the hubs locked and it only did it when i let off the gas?

What do you guys think?

Not "Normal"....

You have a U-Joint/Cardan Joint/Slip Joint issue somewhere.

Take the DriveShaft out (when better weather returns ) and check it all.

Oh Wait, just notices your pic, with that Lift maybe it IS going to be normal for you!

Well how come it only did it in 4x4 not when the hubs were locked? because the drive shaft is still spinning with the hubs locked

Yes, but without any strain on it...

Warn or binding parts sometimes are OK when they're free to do what they want. Once you force them to do their job, take the load, those bad clearances complain
