Removal Procedure
Important: Before disassembly, observe and accurately
reference mark all driveline components relative to the propeller shaft and axles.
These items include the following components:
Assemble all components in the exact relationship to each other as they
were prior to removal. Observe all published specifications and torque values, and
any measurements obtained prior to disassembly.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the transfer case shield, if equipped. Refer to the appropriate
procedure:
- If equipped with the double clamp style
boot, remove the clamp (4) at the transfer case by prying up the exposed end
of the clamp with a flat-bladed tool.
- Reference mark the relationship of the propeller shaft to the front axle
pinon 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.
- Remove the bolts (6) and the yoke retainers (7) from the front
axle pinion yoke (1).
Important: Do not drop the bearing cap assemblies of
the yoke end.
- 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.
- If equipped with the single clamp style
boot, disconnect the boot from the groove on the transfer case output shaft.
- If equipped with the double clamp style
boot, disconnect the boot from the groove on the transfer case output shaft.
- Remove the propeller shaft from the transfer case output shaft by sliding
the propeller shaft forward.
Installation Procedure
- 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 grease, GM P/N 12345879 (Canadian P/N 10953511),
or equivalent lubricant meeting GM Specification 9985830.
- If equipped with the double clamp style
boot, perform the following steps to install the propeller shaft to the transfer case:
2.1. | Install a new clamp in the groove of the propeller shaft boot. |
2.2. | Install the propeller shaft splines in the transfer case output shaft. |
- If equipped with the single clamp style
boot, install the propeller shaft splines into the transfer case output shaft.
- Install the propeller shaft (5) to
the front axle pinion yoke (1).
Align the reference marks made
during removal.
Notice: Refer to Fastener Notice in the Preface section.
- Install the yoke retainers (7) and the bolts (6).
Tighten
Tighten the yoke retainer bolts to 25 N·m
(18 lb ft).
- For both style of boots, install the boot onto the transfer case output
shaft until the boot snaps into the groove on the output shaft.
- If equipped with the double clamp style
boot, use the J 43218
to crimp
the clamp until the dimensions shown are obtained.
- Install the transfer case shield, if equipped. Refer to the appropriate
procedure:
- Lower the vehicle.
