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 wheel drive shafts, 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
obtained prior to disassembly must be followed.
1. Raise the vehicle. Refer to Vehicle Lifting.
2. Remove the transfer case shield, if equipped.
3. If equipped with the double clamp style boot, remove the clamp (4) at the transfer case (3) by prying up the exposed end of the clamp (4) with a
flat-bladed tool.
4. Reference mark the relationship of the propeller shaft (5) to 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.
5. Remove the bolts (6) and the yoke retainers (7) from the front axle pinion yoke (1).
Important: Avoid dropping the bearing cap assemblies of the yoke end.
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.
