Major Transfer case problems maybe

[Chetrick87]

I have an 07 hoe with about 132k on it . Yestersay i backed out of my driveway and heard like a loud clunking/ metal clicking noise for a second. The noise kept happening everytimr i took off from a start, made turns, and went into reverse. The noise was extremely koud and it kind of felt like it was jumping. At first it sounded like it was in the front but then it became more obvious it was the rear. I dropped it off at the shop. He hasnt had a chance to really get into it but he is thinking transfer case? Any thoughts and opinions???? About a month ago i had the rear diff fluid changed and the front. And it has always made a hunning noise when i am giving it gas over 50 mph

Hmmmm.. i had all my internals of my transfer case go in my 12.... im still ocvered under the GM power terrain warranty. but im worried i have a set of XD wheels on it that i have to get off to get it towed to the dealer. The symptoms i was having were loud tire hum from the back, axle was locking up when going around turns.

My 2006 had a cracked internal case in the rear diff with those symptoms.

Turned out that the Spider gears in the rear ddiff are shot
