• Q: How to replace a one-piece Drive Shaft on 2001 GMC Yukon XL 1500?

  A: The replacement of a one-piece propeller shaft requires you to measure all driveline components relative to the propeller shaft and axles before disassembly for the propeller shafts, drive axles, pinion flanges, and output shafts including reference marking operations to preserve their original relationships. The first step involves lifting the vehicle during which you should mark the propeller shaft to match the pinion yoke of the rear axle and the transmission or Transfer Case. The rear axle pinion yoke requires removal of its retaining bolts before its yoke retainers can come out. The yoke ears alongside Universal Joint should remain free from damage because both hitting them with tools or applying force directly will break the injection joints. The skilled installer should first move the propeller shaft in the forward position to eliminate the front connection between the rear axle pinion yoke before shifting it to the rear position for disconnection from transmission or Transfer Case before the vehicle receives its final shaft removal. Check if the Slip Yoke splines have enough grease before installation; if not present, use gm p/n 12345879 or equivalent grease as specified in 2w/d w/ a. T. Only. Only). The propeller shaft installation requires alignment of reference marks from removal before building a connection between the transmission or Transfer Case and the rear axle pinion yoke. During this step normalize the reference marks alignment. Put the yoke retainers into place followed by their bolts , tight them with 25 nm (19 ft. Lbs.) torque then restore the vehicle to the ground.
