A worn or dried out bearing may produce howling or whining noises, and in more serious cases, even grinding noises. The sounds may change in volume or pitch according to the speed of the vehicle.
A little loud, but not unusual. One piece cases are louder than the split cases. It doesn’t whine like a case low on oil. When you get low on oil, you’ll know.

The transfer case is a mechanical component in all four-wheel-drive and all-wheel-drive vehicles. It distributes engine power from the transmission to the front and rear drive shafts, acting as a differential between the front and rear wheels.
A transfer case is part of the drive-train (this includes four-wheel drive, all wheel drive, and other multiple powered axle vehicles). Specifically, this mechanism shifts power from the transmission to the front and rear axles with the power of the drive shaft.
