We fixed a brand new Denali with the same problem. Swapped the entire rear end and the noise/pressure was gone.

Well that is on GM hands they have to help with something the car runs beautiful in 2wd but the rest is just that freaking noise.

Our too we have 20,000 miles without any mayor problem, George I have manor stuff but transfer case is grinding in auto or 4h not every time but is doing. Very annoying.

I wouldn't settle with that Julian. I have two GM trucks right now, and that's never happened to either.
I might think about having them replace the Transfer case.

BTW, how it that nice Florida sunshine?
12 degrees here this morning..

We had a field engineer come out. He said that would've been the last thing he'd thought would be causing it but we did it on the recommendation of another engineer who had the same issue.

We had already checked the ring and pinion TWICE before he came out.

We never really pinpointed the cause but it was something in the rearend.

Got it thanks for the answer, now everything start to come to a problem, but the rare thing is is only on auto or 4h and you feel is come from the front.
With the radio on you don't know if happen. But in silence yes you will.
