What is the rear axle of a car?

The rear axle of a car is a critical component that connects the rear wheels and supports the vehicle's weight while facilitating movement. It transmits power from the engine to the rear wheels, enabling them to rotate and propel the car forward. Additionally, the rear axle plays a vital role in maintaining stability and handling during driving. In many vehicles, it may also house the differential, which allows for differences in wheel speed during turns.
