Section 230 (Rear Driveline Module): Installation
Never grasp half shaft assembly by the boots. This may cause the boot to pucker or crease and reduce the service life of the boot.
Avoid over angulating or stroking the C/V joints when handling the half shaft.
Half shafts exposed to battery acid, transmission fluid, brake fluid, differential fluid or gasoline may cause the boots to deteriorate. Failure to follow these instructions will result in damage.
Propeller shaft installation is a two-person operation. Never allow propeller shaft to hang from the center bearing, or while only connected to the transmission or rear axle flanges. A helper is required. If a propeller shaft section is hung unsupported, damage may occur to the shaft, coupler, and center bearing from over-angulation. This may result in driveline vibrations or component failure.

- If removed, install the Right Hand (RH) halfshaft into the Rear Drive Unit (RDU). Clean any residual excess grease from RDU output shaft.NOTE:
Clean the splined mating surfaces and apply a light grease to the internal splines prior to installing halfshaft.
- Install the RH halfshaft shim onto the hub end of the shaft.
- Secure the RDU on a suitable jack and secure it with chains.
- If service was performed to the RDU and hydraulic fluid needs to be added. Refer to FLUID, DIFFERENTIAL, STANDARD PROCEDURE .
- Raise the RDU with the RH halfshaft into position.NOTE:
There are locating pins on the RDU bracket. Make sure the RDU bracket is in the correct location.
- Guide the RH halfshaft (2) into the RH hub.
- Connect the vent hose (1).NOTE:
The rear sway bar (2) may need to be repositioned to install the rear RDU bracket to isolator through bolt (1).
NOTE:Do not tighten at this time.
- Install rear RDU bracket to isolator through bolt (1) hand tight.NOTE:
The front RDU bracket to isolator bolts (1) must be installed from the front side of the RDU bracket with the nuts on the isolator side.
- Install the four RDU bracket to RDU bolts (2) and tighten to the proper specification. Refer to TECHNICAL SPECIFICATIONS .
- Install the front RDU bracket to isolator through bolts (1) and tighten to the proper specification. Refer to TECHNICAL SPECIFICATIONS .
- Tighten the rear RDU to isolator through bolt (1) to the proper specification. Refer to TECHNICAL SPECIFICATIONS .NOTE:
Clean the splined mating surfaces and apply a light grease to the internal splines prior to installing halfshaft.
- Install the Left Hand (LH) halfshaft (1) onto the RDM. Clean any residual excess grease from RDU output shaft.
- Install the LH halfshaft shim onto the hub end of the shaft.
- Install the LH rear knuckle. Refer to KNUCKLE, REAR, INSTALLATION
.
- Install the RH rear halfshaft hub nut (1) and tighten to the proper specification. Refer to TECHNICAL SPECIFICATIONS
.NOTE:
The six bolts that are used to secure the propeller shaft to the RDU input flange MUST be replaced. Do not reuse the bolts/washers.
NOTE:Use of Anti-seize compound is prohibited.
NOTE:Make sure the double washer is flat/flush to the joint housing prior to tightening the bolt to avoid damage to the washer, if damaged replace bolt washer assembly.
NOTE:No torque verification is allowed after 10 minutes of the bolts being tightened to specifications. ANY MANIPULATION of the bolts after 10 minutes of being tightened will require the bolt(s) to be replaced.
- Connect the propeller shaft to the RDU, align the index marks (3) made during removal, install NEW
rear propeller shaft bolts (1) and tighten to the proper specification. Refer to TECHNICAL SPECIFICATIONS .
- Connect the pump motor wire harness connector (2).
- Connect the pressure sensor wire harness connector (1).
- Install the muffler. Refer to MUFFLER, EXHAUST, INSTALLATION .
- Fill the RDU with differential fluid. Refer to FLUID, DIFFERENTIAL, STANDARD PROCEDURE .
- Remove the support and lower the vehicle.
