Propeller Shaft Replacement - Front
Removal Procedure
Important: Observe the position driveling components. Accurately mark the relationship of the components before removal. These components
include the propeller shafts, the drive axles, the pinion flanges, and the output shafts. Reassemble all components in the exact relationship to each
other as they were before removal. Follow the specifications, the torque values, and any measurements obtained prior to disassembly.
1. Raise the vehicle.
2. Reference mark the relationship of the propeller shaft to the front axle pinion yoke.
3. Remove the yoke retainer bolts and yoke retainers from the front axle pinion yoke.
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
4. Disconnect the propeller shaft from the front axle pinion yoke. Wrap the bearing caps with tape in order to prevent the loss of bearing rollers.
5. Remove the propeller shaft from the transfer case.
Installation Procedure
1. Inspect the splines of the transfer case output shaft for a sufficient coating of grease. If the output shaft does not have a sufficient coating of grease,
lubricate the shaft with P/N 12377985.
Important: Ensure that the propeller shaft assembly is fully engaged into the slip yoke. The retaining ring will produce a snapping noise when the
shaft is properly engaged.
2. Install the propeller shaft to the transfer case.
3. Install the propeller shaft to the front axle pinion yoke. Align the reference marks made during removal.
Notice: Refer to Fastener Notice in Service Precautions.
4. Install the yoke retainers and the bolts.
