How Often Should the Transfer Case Oil in a Prado Be Changed?

[DelPreston]

The transfer case oil in a Prado should be changed every 50,000 to 80,000 kilometers. It is essential to replace the transfer case oil regularly; otherwise, it may lead to damage to the transfer case. Function of the Transfer Case: 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. In vehicles equipped with a transfer case, power is first transmitted from the driveshaft to the transfer case, which then distributes it to the front and rear axles. It allows switching between rear-wheel drive and four-wheel drive and is commonly used in rugged off-road vehicles. Advantages of the Transfer Case: Pure mechanical structure ensures high reliability; enables a 50:50 power distribution; enhances the vehicle's off-road capability. Disadvantages of the Transfer Case: Lacks a differential, making turning impossible in four-wheel-drive mode; no synchronizer, so switching can only be done when the vehicle is stationary.
