Prior to removing the rear propeller shaft technicians must reference-mark the driveline components concerning the propeller shaft and axles including propeller shafts and drive axles and pinion flanges and output shafts so the components can be reassembled in their original arrangement. After lifting the vehicle implement a marking process to link the propeller shaft with rear axle pinion yoke and transmission or Transfer Case. Through the process disconnect the bolts and the retainers from the rear axle pinion yoke. A tool should never be placed between the yoke and
Universal Joint to prevent injection joints from breaking because of the potential damage to the yoke ears during propeller shaft removal. To detach the propeller shaft users should first direct it forward away from the rear axle pinion yoke and secondly slide it toward the transmission or Transfer Case for separation before removing the shaft entirely from the vehicle. Check if the Slip Yoke splines have proper lubrication levels, apply gm p/n 12345879 (Canadian P/N 10953511) lubricant or equivalent gm specification 9985830 (ROOD w/ Automatic Transmission). The installation process of the propeller shaft starts with feeding it through the transmission or Transfer Case while matching reference marks from removal. Subsequently, the shaft slides into rear axle location to join with the pinion yoke through proper alignment of reference points. Lower the vehicle after installing the yoke retainers along with bolts while placing the yoke retainer bolts at 25 nm (19 ft. Lbs. Torque).
