live axle

Spinning drive beam

A live axle is a shaft that transmits power from the drivetrain to the wheels while also supporting the vehicle's weight.

Unlike a dead axle, which merely holds wheels in position, a live axle rotates with the wheels it drives.

The term appears mainly in automotive contexts: Most trucks still use a solid live axle in the rear.

Live axles are simpler and more durable than independent suspension systems but provide a rougher ride.
