How to service the differential cover on a 10.25 Inch Rear Axle on 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.

How to service and repair the differential cover on Ford Mustang?

Start servicing the differential cover by raising and properly supporting the vehicle. The differential housing cover removal becomes possible after uninstalling 10 bolts which enables the draining of lubricant from the rear axle housing. Make sure to wipe down both machined surfaces on the differential housing and the rear axle housing so they are clean of oil then you should apply the new silicone sealant before covering the inside of the rear axle from cleanup contamination. Clear Silicone Rubber F7AZ-19554-CA with equivalent Ford specifications ESB-M4G92-A should be used to make a continuous bead that requires application on the differential housing cover before installation within 15 minutes to prevent additional sealant application. Waiting for an hour until silicone sealant reaches full cure state will be ideal before performing lubricant fill. Place the differential housing cover along with its ten bolts in position before adding SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL or an equivalent brand meeting Ford specification WSP-M2C197-A to the specified level of 3.25 - 3.50 liters (6.9 - 7.4 pints). Complete the procedure by installing the filler plug.

How to service the differential cover of a 8.8-inch ring gear rear drive axle on Ford Ranger?

The servicing procedure for a Ford 8.8-inch ring gear rear drive axle differential cover demands that you place the vehicle in NEUTRAL gear on a hoist. The service begins by removing the differential housing cover using the 10 bolts and afterward draining the lubricant from the differential housing. Clean all machined parts of the differential housing and the cover surface until oil-free contamination is prevented. The installation of the differential housing cover requires applying a continuous AESM silk sealant bead and finishing the task within 15 minutes to prevent sealant replacement. The 10 bolts need a torque of 45 Nm (33 lb-ft) after they are tightly installed. A Traction-Lok axle servicing requires you to add 118 ml of friction modifier prior to adding 2.4L of rear axle lubricant. Secure the filler plug by applying 52 Nm torque. The axle takes one hour to cure before it is safe to add lubricant to it.
