Front axle shafts are flexible assemblies which consist of the following components:

The axle shaft is a balanced shaft that transmits rotational force from the front differential to the front wheels when the transfer case is engaged. The axle shaft is mounted to the front differential by bolting the flange of the axle shaft to the flange on the inner output shaft of the front differential. The other end of the axle shaft is splined to fit into and drive the hub assembly when the transfer case is engaged. The tri-pot joint and constant velocity joint on the axle shaft allows the shaft to be flexible to move with the suspension travel of the vehicle.
