Drive/Propeller Shaft: Description and Operation
Propeller shaft
General
The function of the propeller shaft is to transfer power from the transfer case to the differential clutch. It consists of three pipe sections, a front Rzeppa
joint, two Polhem joints in the center and a rear Rzeppa joint. The propeller shaft's support bearings are fitted by the Polhem joints. The bearings are
mounted in rubber bushings which are fitted in brackets, and these in turn are bolted to the underside of the vehicle. The position of the brackets is
very precisely measured during vehicle manufacture. The propeller shaft does not run in a straight line between the transfer case and the differential
clutch but is instead gently curved, and this is to avoid vibration.
