• Q: How to Service and Repair the 9.75 Inch Rear Differential Cover on 2004 Ford E-250?

  A: A Ford 9.75 Inch Rear Differential requires beginning service and repair activities after positioning the vehicle at a hoist with the transmission in NEUTRAL position. Start servicing the Ford 9.75 Inch Rear Differential by first removing its cover through the removal of 12 housing bolts followed by draining the axle housing lubricant. Both the rear axle housing and differential housing cover require cleaning with oil-free surfaces before receiving silicone sealant application while you need to block the inside of the rear axle from contact with contaminants. Every gasket mating surface requires cleaning before applying an unbroken bead of sealant onto the differential housing cover. There is a time restriction for installing the cover after silicone application which is 15 minutes; if this period exceeds the sealing surface requires new cleaning and fresh sealant application. The silicone sealant needs one hour of curing time before the addition of lubricant. Position the differential housing cover before securing all bolts to their proper tightness. Add the specified additive friction modifier into the rear axle at the level of 118 ml (4 ounces) before filling with the stated rear axle lubricant that stays below the filler hole opening. Install the filler plug afterward.
