What causes oil leakage in the Prado transfer case?

[VanMargaret]

Oil leakage in the Prado transfer case is caused by aging of the sealing gasket. Function of the transfer case: The main function of the transfer case is to reasonably distribute the power of the engine, delivering power to the rear axle or simultaneously to both the front and rear axles. It enables switching between different driving modes, such as changing a four-wheel drive vehicle to two-wheel drive. Precautions: The transfer case contains specialized gear oil, which should be replaced regularly. It is recommended to replace it when the vehicle has traveled approximately 60,000 to 80,000 kilometers. When switching driving modes using the transfer case, it is best to do so when the vehicle is stationary to prevent wheel reaction forces from damaging the transfer case.
