  Q: How to service and repair the 9.75-inch ring gear differential cover on Ford E-150 Econoline?

  A: Vehicle service and differential cover repair of the 9.75-inch ring gear requires first that the vehicle receives a lift followed by vehicle support. Drain the lubricant into a clean container at first and then remove the differential housing cover by unfastening its 12 bolts. Apply new silicone sealant to the surfaces of the rear axle housing and differential housing cover when they are freed from oil while constantly maintaining protective coverage of the rear axle interior from atmosphere. The installation process requires a continuous bead of Silicone Rubber D6AZ-19562-AA or equivalent according to Ford specifications ESB-M4G92-A and ESE-M4Gl95-A to be applied on the differential housing cover. Installation of the cover needs to happen within 15 minutes of silicone application time or else the sealant will require replacement. Before filling the lubricant container it is necessary to wait one full hour for the silicone sealant to reach full cure. Secure the differential housing cover bolts after its installation. The rear axle of Traction-Lok systems requires 118 ml (4 ounces) of Ford Additive Friction Modifier C8AZ-1911546-A or a matching product that follows Ford specification EST-M2C118-A. After adding this solution, use SAE 75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B which follows WSL-M2092-A Ford specification and reinstall the filling plug prior to lowering the vehicle.
