How does a power transfer unit work?

A power transfer unit, also known as a transfer case, is an essential component in four-wheel drive vehicles that allows for power to be distributed between the front and rear axles. It works by taking power from the vehicle's transmission and directing it to both the front and rear wheels through a series of gears and shafts. In four-wheel drive mode, the power transfer unit engages both the front and rear axles to ensure maximum traction and stability on rough or slippery terrain. By transferring power to all four wheels, the power transfer unit helps improve the vehicle's off-road performance and maneuverability.
