Rear Driveline Module: Description
The rear driveline module assembly (Fig 1 ) consists of four main components:
- Bi-Directional Overrunning Clutch (BOC)
- Viscous Coupling
- Differential Assembly
- Torque Arm
The viscous coupling and bi-directional overrunning clutch are contained within an overrunning clutch housing, which fastens to the differential assembly. The overrunning clutch housing and differential assembly have unique fluid sumps, each requiring their own type and capacity of fluid. The overrunning clutch housing requires Mopar(R) ATF+4 (Automatic Transmission Fluid-Type 9602) or equivalent.
Driveline module service is limited to the following components:
- Differential Assembly (serviced only as assembly)
- Viscous Coupling
- Bi-Directional Overrunning Clutch (BOC)
- Overrunning Clutch Housing
- Seals (Input Flange, Output Flange, Overrunning Clutch Housing O-rings)
- Input Flange/Shield
- Torque Arm
- Vents
- Fasteners
