How to service and repair the rear drive axle shaft and differential of a 8.8-inch ring gear on 2009 Ford Mustang?

You should start servicing and repairing a Ford 8.8-inch ring gear rear drive axle and differential by setting the vehicle into neutral position with a hoist underneath it. Begin service on the differential housing by first removing its cover and breaking disc. Before proceeding to the U-washer you must remove and safely place the rear wheel speed sensor because it could get damaged. The service requires removing of the differential pinion shaft through lock bolt removal followed by shaft extraction. You need to carefully take out the axle shaft U-washer without destroying the rubber O-ring inside the axle shaft grooves through a method where you push the axle shaft inward before removing the U-washer. The removal of the axle shaft should occur without damaging the axle shaft oil seal. The lip of the oil seal on the axle shaft requires greasing before axle shaft installation while ensuring the seal stays intact. To install the U-washer place it onto the button section of the axle shaft and extract the axle shaft farther out. Replace the differential pinion shaft by inserting the hole into the differential case lock bolt hole before tightening it with a new lock bolt to 30 Nm (22 lb-ft). Secure the rear wheel speed sensor by installing its bolt after tightening it to 15 Nm (133 lb-in). Reposition both components in their proper places before hanging up the differential housing cover and rear brake disc.
