Most likely a bearing in rear end. Pinion or wheel bearings. Have a good independent shop install noise sensors located at each bearing location to verify which one it is. Oh yes I'm assuming you have done the obvious check it for proper level of lubrication in the rear end.

Check to see if the drum is hotter than normal. If the bearings are bad, you have to lift the truck and remove the axle. Remove the wheel drum until you get to the axle. They to remove the axle, you have to open the rear end Spider gear ***** at the middle. They have a half moon wedge or a clip you have to remove. They you pull out the axle.Replace the bearing grease it and seal it. Then put it back in the reverse order. Sounds simple but it is not that simple. Takes work

sounds like the clip on the rear output shaft its probably broke. do this by removing the rear driveshaft, and the tail of the transfer case, there are 4 bolts holding it in place. then grab the output shaft and see if it has any front to back movement. if so pull it all the way to the rear and you should see a groove at the front part of the shaft where the clip goes. Then you should find the pieces fo the clip in the tail housing. One person said he found the replacement clip at a local tranny shop. I am calling the dealership parts counter for a new clip for my 97 Tahoe tomorrow. Hope this helps..

I say it's the CV joints. You have to jack up under the lower A-Arm, to take the spring pressure off of it, to check them.
(Use jack stands, and wheel chocks behind the rear tires. Emergency brake On. Work on a hard level surface. Be SAFE! Trucks can be replaced, YOU cannot!)

Sounds like the chain in the transfer case has broke or the linkage is out of adjustment
