  Q: How to replace a one-piece Drive Shaft on GMC C3500?

  A: The first step when replacing a one-piece propeller shaft requires precise reference marking of all driveline elements against the propeller shaft alongside axles including propeller shafts and drive axles and pinion flanges and output shafts to respect their original placement. Start with marking connections between propeller shaft and pinion flange along with Slip Yoke to transmission. Service driveshafts using the pop-on seal by keeping the seal inside its sleeve since removing it may harm the lip. In case the seal needs removal, install a brand-new unit. The removal of both bolts and retainers should be conducted while avoiding forceful contact on the yoke ears together with preventing insertion of tools between the yoke and Universal Joint to prevent fracture of the injection joints. Lower the propeller shaft forward while sliding it out but avoid extreme tilt of the Universal Joint. Complete this process by wrapping the bearing cups in tape to stop bearing rollers from falling out. During front propeller shaft service always support the shaft while preventing excessive bending of its Universal Joint. All parts need cleaning with an approved solvent followed by checking the transmission yoke outer diameter for burrs and inspecting the Slip Yoke splines for wear to determine the absence of twisted splines and incorrect universal joints. The Universal Joint bearing should be inspected for wear signs before conducting any replacement needs. Insert the propeller shaft into the transmission before using chassis grease on the splined slip joint and then align reference marks on the pinion flange with the propeller shaft rear yoke followed by installing the yoke cross assembly onto the fixed yoke before securing retainers and bolts to 20 nm (15 ft. Lbs.) torque.
