Noise problems are more difficult to diagnose and service than mechanical failures.
Before taking the transfer case to specialist, check if the hub on the opposite side of the axle is not desengaging. That can happend when dirt and water enter the hub and contaminate the lubricant.
If noise comes from transfer case, check for incorrect tire inflation or tire size, excessive tire wear,
It many different transfer cases in used today and each has its own features characteristic and servivce procedure. Proper diagnostics and service beging with the proper indentification of the transfer case.
Like Jack said from the begining, take it to spesialists.
