The propeller shaft connects to the differential clutch driver by means of the rear drive shaft universal joint which is bolted to the driver with 6 bolts.
The function of the joint is to handle the difference in angle between differential clutch driver and propeller shaft, as well as to be flexible
longitudinally. The extent of the joint's longitudinal movement is 8 mm. The rear drive shaft universal joint is also a Rzeppa joint and is friction
welded to the rear pipe section and constitutes one unit together with the propeller shaft.
