Propeller Shaft Replacement- Front

^ Tools Required
- J 43218 Clamp Pliers Narrow Jaw

Removal Procedure





Important: Before disassembly, observe and accurately mark all of the driveline components relative to the propeller shaft and to the axles. These items include the following components:
^ The propeller shafts
^ The wheel drive shafts
^ The pinion flanges
^ The output shafts

Assemble all of the components in the exact relationship to each other prior to removal. Observe all published specifications and torque values, and any measurements obtained prior to disassembly.
1. Raise the vehicle. Refer to Vehicle Lifting.
2. Remove the transfer case shield, if equipped.
3. Mark the relationship of the propeller shaft and of the front axle pinion yoke.
4. Remove the clamp (4) at the transfer case (3) by prying up the exposed end of the clamp (4) with a flat-bladed tool.





5. Remove the bolts (6) and the yoke retainers (7) from the front axle pinion yoke (1).

Notice: 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.

6. Disconnect the propeller shaft (2) from the front axle pinion yoke (1).
Wrap the bearing caps with tape in order to prevent the loss of bearing rollers.

Important: Do not drop the bearing cap assemblies of the yoke end.

7. Remove the propeller shaft (5) from the transfer case output shaft by sliding the propeller shaft forward.

Installation Procedure





1. Inspect the splines of the transfer case output shaft for a sufficient coating of lubricant. If the output shaft does not have a sufficient coating of lubricant, lubricate the shaft with lubricant GM P/N 12345879 (Canadian P/N 10953511) or with an equivalent lubricant meeting GM specification 9985830.
2. Install the new clamp into the groove of the propeller shaft boot.
3. Install the propeller shaft splines into the transfer case output shaft.





4. Install the propeller shaft (5) to the front axle pinion yoke (1).
Align the reference marks that were made during removal.

Notice: Refer to Fastener Notice in Service Precautions.

5. Install the yoke retainers (7) and the bolts (6).
^ Tighten the yoke retainer bolts to 25 Nm (19 ft. lbs.).
6. Install the boot onto the transfer case output shaft until the boot is attached into the groove on the output shaft.





7. Using the J 43218 crimp the clamp until the dimensions that are shown are obtained.
8. Install the transfer case shield, if equipped.
9. Lower the vehicle.
