How to service and repair the differential cover on a 7.5-Inch Ring Gear Rear Drive Axle on Ford Mustang?

The first step for servicing or repairing the differential cover of a Ford 7.5-Inch Ring Gear Rear Drive Axle requires the vehicle to be in neutral position on a hoist. You should start by taking out the 10 differential housing cover bolts and extracting the lubricant from the axle housing. During service the machined surfaces need proper cleaning to remove all oil residue as a way to stop contamination of both the differential housing and the differential housing cover. The inner section of the axle must remain covered. Use a particular silicone sealant thickness for a continuous bead around the differential housing cover before installing it within a 15-minute period to prevent sealant reapplication. The differential housing cover requires bolt tightening to 46 Nm when completely installed. Fill the axle while the vehicle sits on a flat surface at its normal ride height using up to 1.42 liters of required axle lubricant and stop adding fluid 11.1 to 12.7 min below the fill hole's bottom before tightening the filler plug to 30 Nm torque.
