Propeller Shaft Replacement - Two Piece
Tools Required J 43218 Clamp Pliers-Narrow Jaw
Removal Procedure
IMPORTANT:Observe and accurately reference mark all driveline components relative to the propeller shaft and axles before disassembly. These components include the propeller shafts, the drive axles, the pinion flanges, the output shafts, etc. All components must be reassembled in the exact relationship to each other as they were when removed. In addition, published specifications and torque values, as well as any measurements made prior to disassembly must be followed.
Raise the vehicle. Refer to JACKING AND LIFTING.
Reference mark the rear propeller shaft (3) to the rear axle pinion yoke (4). Reference mark the front propeller shaft to the transmission or transfer case (slip yoke type) or to the transmission pinion yoke (universal joint type). Fig. 22: Rear Propeller Shaft & Rear Axle pinion Yoke
Remove the clamp (2) securing the boot (3) to the front propeller shaft stub shaft (4) and the rear propeller shaft slip yoke (1) by prying up the exposed end of the clamp (2) using a flat bladed tool (if applicable). Fig. 23: Rear Propeller Shaft Slip Yoke, Front Propeller Shaft Stub Shaft, Clamp & Boot
Remove the bolts (1) and the yoke retainers (2) from the rear axle pinion yoke (4).

Remove the bolts (1) and the yoke retainers (2) from the rear axle pinion yoke (4).
NOTE:When removing the propeller shaft, do not attempt to remove the shaft by pounding on the yoke ears or using a tool between the yoke and the universal joint. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint.
Slide the rear propeller shaft forward in order to remove the propeller shaft from the rear axle pinion yoke. Slide the rear propeller shaft rearward in order to disconnect the rear propeller shaft from the front propeller shaft stub shaft.
Remove the rear propeller shaft from the vehicle.
Remove the boot from the front propeller shaft stub shaft (if applicable). Fig. 24: Rear Axle Pinion Yoke, Yoke Retainers & Bolts
Remove the center bearing support nuts (1).
Remove the center bearing support (2). Fig. 25: Center Bearing Support & Nuts
Remove the front propeller shaft by sliding the front propeller shaft rearward from the transmission or the transfer case, w/o RPO MW3 or M74. Fig. 26: Remove Front Propeller Shaft Courtesy of GENERAL MOTORS CORP.
Remove the bolts and the yoke retainers from the transmission pinion yoke, w/RPO MW3 or M74. Remove the front propeller shaft by disconnecting the front propeller shaft from the transmission pinion yoke, w/RPO MW3 or M74. Fig. 27: Yoke Retainers & Bolts

Propeller Shaft Center Support Bearing Replacement Removal Procedure Raise the vehicle. Refer to JACKING AND LIFTING. Remove the propeller shaft. Refer to Propeller Shaft Replacement - Two Piece. Remove the center bearing by doing the following: 3.1. Stand the propeller shaft (2) on end in the press (1) with the center bearing (3) supported by the press bars (4). 3.2. Press the propeller shaft (2) down and off the center bearing (3). Fig. 34: Propeller Shaft, Center Bearing, Press & Press Bars
Installation Procedure
Install the center bearing (3) onto the propeller shaft (2) by pressing the center bearing onto the shaft using a press (1). Install the propeller shaft. Refer to Propeller Shaft Replacement - Two Piece. Lower the vehicle. Fig. 35: Propeller Shaft, Center Bearing, Press & Press Bars
