How Often Should Transfer Case Oil Be Changed?

[Morales]

Transfer case oil should be changed every 50,000 to 80,000 kilometers. The consequences of not changing the transfer case oil for an extended period include: 1. Accelerated wear of the gears inside the transfer case; 2. Damage to the transfer case; 3. Reduced lubrication performance, leading to the accumulation of metal debris in the oil. The transfer case is a device that distributes the engine's power, directing it to the rear axle or simultaneously to both the front and rear axles. The working principle of the transfer case is as follows: after the engine's power passes through the transmission, it is directly connected to the rear axle via the driveshaft. The transfer case then extends an additional output from the transmission, using a silent chain to transfer power to the front axle's output shaft.
