The axle shafts are part of the axle assembly. It is simply a rotating or revolving shaft that turns the wheels. The axle shaft is also called the half shaft and come in a variety of shapes and sizes to suit the specific application. The axle bearing is connected to the inner end of the axle shaft and is connected to the differential or transmission of the vehicle. The axle shafts are responsible in supporting and aligning the axle shaft for a smoother operation. Adding power to the engine will require a stronger, lighter, and more dependable set of axle shafts.
