Dealership proprietary knowledge

[Bud2014]

Truck is still in the dealership. Has been there for almost two weeks. Have brought it in questioning the transmission shifting hard or high rev before shifting. Dealer said nothing was wrong and sent me on my way re-setting it by disconnecting the battery. Now its not in for that. It is in for the loud wheel noise that was coming through the floorboatd. Roaring and grinding sound. Dealer put the scope to find the issue. Replace hub assemblies. Went home with truck then a new noise started a day later . Sounds like meta in a bender and also sounds like it may have a vacuum problem and will not allow 4x4 to disengage. The dealer was clueless . Getting a leak test done to the locking and unlocking hubs. What does this sound like?
