A transfer case is a crucial component in four-wheel drive (4WD) and all-wheel drive (AWD) vehicles. Its primary function is to distribute power from the engine to both the front and rear axles, enabling all four wheels to drive the vehicle.
Here are some key points about what a transfer case does:
Power Distribution: It transfers power from the transmission to the front and rear axles, ensuring that all wheels receive power.
Mode Selection: It allows the driver to switch between two-wheel drive (2WD) and four-wheel drive (4WD) modes. Some transfer cases also offer a low-range gear for better torque in off-road conditions.
Synchronization: In AWD systems, the transfer case helps synchronize the rotation of the front and rear wheels, which is essential for smooth driving on various terrains2.
Without a transfer case, a 4WD or AWD vehicle wouldn’t be able to function properly. It’s especially important for off-road driving, towing, and handling difficult driving conditions like snow or mud.
