Does the truck have a lift kit on it? Also have you checked to see if the Rearend is vented or if it has a plastic plug left in it the differential? It should have a check valve at the top right for thermal expansion. Mine had a plug and the dealer tried to tell me it was normal even though I showed him the service bulletin. I bought some braided stainless steel hose from Ace hardware and vented it my self.
There is also a service bulletin for the front to make sure their are no loose bolts. I can't remember if it is only for 4 wheel drives or both. Either way that is not normal and sounds expensive.
I have had some dealers that need to be selling Yugo's and some that are great. If you can't get the dealer to do anything try to find a 4-wheel parts store they should be able to give you an idea of exactly what the noise is.
Sorry I wasn't more help.
