How to Service and Repair the Rear Axle Shaft and Differential of a 7.5-Inch Ring Gear on 2009 Ford Mustang?

Your first step for servicing and repairing a Ford 7.5-inch ring gear rear drive axle and differential should start by hoisting the vehicle with its transmission set in neutral. Start the process by separating the differential housing cover and the rear brake disc from the process. Before beginning U-washer removal from the axle shaft you need to separate the rear wheel speed sensor by unbolting it while keeping it secure aside. Proceed to remove the differential pinion shaft after discarding its lock bolt and pulling out the shaft. Use care while removing the axle shaft U-washer because pressing on the axle shaft will help protect the rubber O-ring at its corresponding grooves when removing the washer properly. Remove the axle shaft from the differential by protecting both the axle shaft oil seal and rubber O-ring of the grooves. Apply grease to the lip of the new axle shaft oil seal before installing the axle shaft with attention to avoid damaging it. You should place the U-washer on the button end of the axle shaft before drawing the shaft outward. Install the differential pinion shaft by putting the hole in the way of the differential case lock bolt hole then fasten this with a new lock bolt torqued to 30 Nm (22 lb-ft). Position the rear wheel speed sensor while tightening its bolt to 15 Nm (133 lb-in). The last step includes reinstalling both components of the rear brake disc and differential housing cover.
