• Q: How to Service the 8.8 Inch Rear Differential Cover on 2004 Ford E-250?

  A: Service of the Ford 8.8 Inch Rear Differential starts by placing the vehicle in the neutral gear and mounting it on a hoist. The removal of the housing cover begins with unscrewing 10 bolts followed by draining the lubricant from the rear axle housing. Both the rear axle housing and differential housing cover need their machined surfaces cleaned completely free of contaminants to receive new silicone sealant after which you should protect the rear axle interior from getting dirty during this operation. Position an ongoing bead sealant onto the differential housing cover gasket mating area when it is clean. The installation of the cover begins right after applying silicone sealant because surface contact needs either immediate placement or new silicone application with cleaning. The curing process of silicone sealant should take one hour before adding lubricant into the system. The 10 bolts should be used to secure the differential housing cover after proper placement on the back axle. The process to fill traction-lok axles includes usage of 118 ml (4 oz) of friction modifier which needs application before you add specified rear axle lubricant and reinstall the filler plug.
