The propeller shaft is a two piece tube supported by a sealed for life centre bearing and non-servicable universal joint. Only vehicles fitted with 4-speed transmissions have a splined slip yoke at the front of the propeller shaft which slides directly into the transmission. The splined slip yoke type propeller shaft has a sealed for life centre bearing and non-servicable universal joint. It has a rubber coupling at each end joining the propeller shaft to the transmission and the differential. All propeller shafts are fixed to the rubber couplings by 3 bolts and 3 torque prevailing nuts which are discarded when removed. Torque prevailing nuts have a low friction coating to ensure no damage to the coupling when assembled, correct nuts must be used. The rubber couplings are then mounted to the differential with 3 bolts and the transmission with 3 bolts and 3 torque prevailing nuts which are also discarded when removed. The centre bearing assembly is fixed to the body with 2 bolts. The two-piece propeller shaft is used to transmit power from the transmission to the differential. The centre bearing and rubber couplings are used to support and connect the propeller shaft and decrease vibration, noise and harshness.
