Propeller Shaft Description and Operation

The propeller shaft assembly is a 2-piece design. The front shaft consists of a plunging A-type constant velocity joint at the front and a universal joint and yoke at the rear.

The rear shaft consists of a centre bearing and a centre yoke, which are pressed onto the rear half of the propshaft and retained by a circlip. The front and rear shafts are joined together at the yokes with a universal joint. The rear shaft attaches to the axle with a flange which is attached to the rear shaft with a universal joint.

The centre bearing provides support where the front and rear shafts mate and is bolted to the underbody. The front constant velocity joint is bolted to the transfer case, and the rear universal joint flange is bolted to the clutch coupling assembly. If any the propeller shaft assembly components fail, the propeller shaft must be replaced as an assembly.
