- Clean the gasket mating surface of the rear axle and the differential housing cover.
- Apply a new, continuous bead of sealant to the differential housing cover.
- Use Silicone Rubber D6AZ-19562-AA or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A.
- Install the differential housing cover and tighten the bolts.
- Fill the rear axle with SAE 75W-140 High Performance Rear Axle Lubricant
F1TZ-19580-B or equivalent meeting Ford specification WSL-M2C192-A, and install the filler plug.
- Lower the vehicle.
CAUTION:
Make sure the machined surfaces on both the rear axle housing and the differential housing cover are clean and free of oil before applying the new silicone sealant. The inside of the rear axle (4001) must be covered when cleaning the machined surface to prevent contamination.
NOTE:
The differential housing cover must be installed within 15 minutes of application of the silicone, or new sealant must be applied. If possible, allow 1 hour before filling with lubricant to make sure the silicone sealant has correctly cured.
CAUTION:
For Traction-Lok® axles, first fill the rear axle with 118 ml (4 ounces) of specified Ford Additive Friction Modifier C8AZ-19B546-A or equivalent meeting Ford specification EST-M2C118-A.
NOTE:
Refill capacities are determined by filling the rear axle with the specified lubricant to the specified level below the bottom of the filler hole.
