This can be a fault with the front differential or transfer case causing this noise here.I can say most common that I have seen before cause this issue can be the transfer case as the bearings in it can fail and under load with the weight of the vehicle on the ground this can cause this noise.
Both the front differential and transfer case will need checked into and may require using an automotive stethescope to listen to any abnormal noises in either of these to locate which is the cause here,then that affected gear box will need removed and taken apart for inspection and repair.
