How to service the differential cover on a 10.25 Inch Rear Axle on 2003 Ford F-150?

A Ford 10.25 Inch Rear Axle differential cover service requires vehicle elevation followed by bolt removal from the 12 housing cover bolts and subsequent drain of rear axle housing oil. You should remove the differential housing cover after completing the drainage process. The machined surfaces of both the rear axle housing and differential housing cover need to be cleaned thoroughly of all oil residue before silicone sealant application creates a continuous bead on the differential cover. The differential housing cover needs installation within 15 minutes after silicone application because delayed installation requires sealant reapplication. Proper silicone sealant curing requires 1 hour waiting time prior to adding lubricant into the system. The rear axle filler procedure requires the specified lubricant to be added after installing the differential housing cover bolts and putting in the filler plug. Prior to adding lubricant into Traction-Lok axles you need to add 236.5 milliliters (8 ounces) of additive friction modifier. Finally, lower the vehicle.
