DESCRIPTION AND OPERATION

WHEEL DRIVE SHAFTS DESCRIPTION AND OPERATION

Front Wheel Drive Shafts are flexible assemblies which consist of the following components:

Front wheel drive shaft constant velocity joint (outer joint).

Front wheel drive shaft tri-pot joint (inner joint).

The front wheel drive shaft connects the front wheel drive shaft tri-pot joint and the front
wheel drive shaft constant velocity joint.

The front wheel drive shaft tri-pot joint is completely flexible and moves with an in and out
motion.

The front wheel drive shaft constant velocity joint is flexible but can not move in and out.

The Wheel Drive Shaft is a balanced shaft that transmits rotational force from the front
differential to the front wheels when the transfer case is engaged. The wheel drive shaft is
mounted to the front differential by bolting the flange of the wheel drive shaft to the flange on the
inner output shaft of the front differential. The other end of the wheel drive 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 wheel drive shaft allows the shaft to be flexible to move with the suspension
travel of the vehicle.
