What is a transfer case used for

A transfer case is a gearbox that directs power to both the front axle and the rear axle of a four-wheel drive vehicle. In a four-wheel drive vehicle, power is normally distributed to the rear wheels, but a transfer case allows power to be distributed between the front and rear axles at the same time.


The transfer case is located behind the transmission, just in front of the center of the vehicle.


After the power is transmitted from the engine to the transmission, the power is then channeled through the transfer case, which can send the power only to the rear wheels or to the front wheels and the rear wheels simultaneously if a four-wheel drive is activated by the driver.


In situations where a rear-wheel drive vehicle may become stuck due to a lack of weight on the drive wheels, a transfer case allows the vehicle to pull itself using the front axle while simultaneously pushing from the axle. rear.


When changing a transfer case between two- to four-wheel drive modes, be sure to follow the manufacturer’s recommendations. Shifting the transfer case too high can cause powertrain damage, which could render your vehicle inoperable.


A transfer case is a mechanical device and in order to stay properly lubricated, it is required to have regular drainage and filling. Follow the recommendations outlined in the owner’s manual.
