REAR DRIVE AXLE DESCRIPTION AND OPERATION

Fig. 51: View Of Rear Drive Axle Assembly

The rear drive axle assembly in this vehicle consists of an aluminum housing which contains an electric clutch which is located in the driveline torque tube (for vehicles equipped with all wheel drive AWD only) and separate from the rear drive. The differential fluid is only contained in the rear drive axle portion of the rear differential assembly.

The clutch assembly for AWD vehicles is serviced separately from the driveline torque tube assembly. The clutch control module (CCM) is located on the torque tube housing and is also serviced separately.

The clutch assembly contains automatic transmission fluid (ATF). There is a seal that protects the driveline torque tube from the ATF contained inside the clutch assembly. Another seal protects the clutch assembly from gear oil.

The fluid level range for proper rear drive axle assembly operation is 0.8 to 1.0 liter depending on the housing design (location of the fill/inspection pug). New service replacement units will be shipped dry (without fluid).

Fill new units with 0.8 liter of GL Synthetic fluid. More importantly, the minimum fluid level should be even with the bottom of the fill hole.

The driveline torque tube houses the third section of the propeller shaft for packaging purposes only. There is one bearing at each end of the torque tube assembly.

The rear drive axle system operates as follows:
