The process of front propeller shaft replacement begins by acquiring the clamp pliers - narrow jaw (J 43218) as one necessary tool. The reinstallation process requires accurate reference marking of all driveline components that relate to the propeller shaft and axles which includes propeller shafts and wheel drive shafts and pinion flanges as well as output shafts for proper reassembly alignment. You must elevate your vehicle and separate the Transfer Case clamp through natural tool opening of its exposed end with a flat-bladed tool. The technician should create reference points that show the alignment status between the propeller shaft and front axle pinion yoke. Protection of the injection joints requires not striking the yoke ears manually or inserting any tools between the yoke and
Universal Joint. Detach all bolts and yoke retainers from the front axle pinion yoke and manage the bearing cap assemblies to prevent loss. The propeller shaft should be detached from the front axle pinion yoke before applying tape around each bearing cap to safeguard rollers from loss. Detach the propeller shaft by first removing its boot from the Transfer Case output shaft groove and moving the shaft forward to separate it. After securing each bearing cap with tape replace the boot. To proceed with the inspection remove any boot clamp from the propeller shaft boot along with the boot itself. Check the splines of the Transfer Case output shaft for appropriate lubricant before applying grease, gm p/n 12345879 (Canadian P/N 10953511), or equivalent lubricant which meets gm specification 9985830. After booting and clamping the propeller shaft boot you should slide the propeller shaft into the Transfer Case output shaft using the splines. The propeller shaft requires reinstallation to the front axle pinion yoke while you align reference marks established when removing it. Install the yoke retainers followed by bolts and tighten yoke retainer bolts to 25 n.m (18 lb ft). At last fit the boot onto the Transfer Case output shaft until the groove receives it and use clamp pliers - narrow jaw (J 43218) to crimp both clamps before lowering the vehicle.
