DIAGNOSIS

1. Raise the vehicle on a lift, then disconnect the rear differential oil pump motor 2P connector.
2. Lower the vehicle.
3. Start the vehicle. Apply the brake pedal, put the transmission in gear, and listen for the noise as soon as you release the brake.
   • If there is no noise, go to REPAIR PROCEDURE.
   • If the noise is still present, this bulletin does not apply. Continue with normal troubleshooting.

 

REPAIR PROCEDURE

1. Raise the vehicle on a lift.
2. Disconnect the breather hose from the pump motor breather pipe.

 

3. Remove the harness clip and the harness bracket.
4. Remove the rear differential pump motor and the O-ring.

 

5. Cut a 1 ¾ inch length of the hard wall clear PVC tubing and chamfer the newly cut edges.

NOTE: The tubing will be used as a guide to install the new intermediate oil pump drive joint and prevent it from falling into the differential assembly where it cannot be removed.

6. Insert the hard wall PVC tube guide you just cut into the oil pump hole and center it over the internal oil pump drive shaft.

 

7. Insert the new intermediate drive joint into the PVC guide as shown.

 

8. With the PVC guide still in place, use a stubby flathead screwdriver to rotate the intermediate drive joint until it fully engages into the internal oil pump drive shaft.

 

9. Carefully remove the guide from the oil pump hole by slowly pulling it straight out.

NOTE: If the intermediate drive joint pulls out of place, it may fall into an area where it cannot be removed without additional differential disassembly.

10. Use a small telescoping mirror to verify that the new intermediate drive joint is still in place.
11. Align the pump shaft to the new intermediate drive joint. Then install the new rear differential pump motor with a new O-ring and torque the bolts to 12 N∙m (9 lb-ft).

 

12. Connect the connector.

 

13. Install the harness bracket and torque the bolts to 12 N∙m (9 lb-ft). Then install the harness clip.

 

14. Connect the breather hose to the pump motor breather pipe.
