  Q: How to service the differential cover of a 9.75-inch ring gear rear drive axle on Ford E-250 Econoline?

  A: You need to raise the vehicle before supporting it for differential cover service of a Ford 9.75-inch ring gear rear drive axle. The service procedure involves draining lubricant into a reusable container after the removal of 12 bolts along with the differential housing cover. Clean both the rear axle housing and differential housing cover surfaces with special attention to prevent contamination by covering the inside of the rear axle. Then apply new silicone sealant to these surfaces after cleaning and before closure. Prepare the gasket mating areas of the rear axle and differential housing cover before applying Silicone Rubber D6A-Z-19562-AA or equivalent materials according to ESB-M4G92-A and ESE-WG195-A Ford specifications. Application of silicone must occur on the differential housing cover within a 15-minute time frame or the process requires using new sealant. Prolonged filling with lubricant must wait for 1 hour after silicone sealant application to achieve complete curing. Fasten the differential housing cover by installing its bolts. Traction-Lok axles require a lubricant filling of 118 ml (4 ounces) Ford Additive Friction Modifier C8AZ-19B546-A (which meets EST-M2C118-A) and subsequently need SAE 75W-140 High Performance Rear Axle Lubricant FITZ-19580-B or an equivalent that meets WSL-M2CI92-A before installing the filler plug when lowering the vehicle.
