Does the vehicle transfer case require oil change?

[McLila]

Yes, the vehicle transfer case requires oil changes, with a recommended interval of 50,000 to 80,000 kilometers. The transfer case is a device that distributes the engine's power, capable of delivering power to the rear axle or simultaneously to both the front and rear axles. The transfer case has two drive shafts: one connects to the front axle, and the other to the rear axle. Typically installed on four-wheel-drive vehicles and connected to the transmission, the transfer case extends an additional output shaft that transmits power to the front axle's output shaft via a silent chain. In vehicles equipped with a transfer case, power is first transmitted from the drive shaft to the transfer case, which then distributes it to both the front and rear axles, allowing for switching between rear-wheel drive and four-wheel drive. This system is commonly used in rugged off-road vehicles.
