SUBJECT:

OVERVIEW:
This bulletin involves installing an auxiliary differential vent and changing the differential fluid.

DISCUSSION:
An auxiliary vent tube assembly has been released for service to provide improved differential case venting. In cold climate areas, under certain driving conditions, pressure can build up in the differential case forcing fluid out through the primary vent tube at the top of the differential. Fluid can collect on the top of the differential case and or drip to the ground.

SYMPTOM/CONDITION:
Differential fluid buildup near the differential vent and/or dripping on the ground.

DIAGNOSIS:
Inspect the top of the differential for fluid. Fluid may drip down the side to the ground.

PARTS REQUIRED:
1 05011589AA Vent Tube Assembly Kit
1 04549624 Mopar 75W-90 Gear Lubricant, 32 oz.

REPAIR PROCEDURE:

1. Clean all fluid from the differential case.
2. Drain the differential fluid by removing the differential drain and fill plugs.
3. Install the differential drain plug. Tighten to 7 Nm (60 in. lbs.).
4. Fill the differential with 32 ounces of Mopar 75W-90 Gear Lubricant, p/n 04549624.
5. Install the revised differential fill plug from the vent tube kit. Tighten to 47 Nm (35 ft.lbs.).





6. Install the new vent tube assembly into fill plug and orient the tube between ribs on the differential cover (Figure 1).
