How to Service and Repair the Rear Axle Shaft and Differential of a 7.5-Inch Ring Gear on 2008 Ford Mustang?

The Ford 7.5-inch ring gear axle differential service requires first placing the vehicle on a hoist with neutral transmission while performing repair operations. Disassemble the differential housing cover and the rear brake disc from the system. Dismantle the rear wheel speed sensor before removing the axle shaft U-washer because damaging the rear brake anti-lock sensor can occur. Proceed to remove the differential pinion shaft after discarding its lock bolt and extracting the shaft. The axle shaft U-washer must come out gently while protecting the rubber O-ring inside the axle shaft grooves by applying pressure to the axle shaft before extraction. Extract the axle shaft in a way that protects both the oil seal and its undamaged condition. The installation process requires you to grease the axle shaft oil seal lip followed by axle shaft installation which should be performed without seal damage. To secure the U-washer on the axle shaft button end you should pull the shaft outward. A replacement differential pinion shaft lock bolt may not be available but the existing bolt can be treated with Threadlock(R) and sealer followed by installation into the differential pinion shaft position with correct alignment to the differential case lock bolt hole and use of a new lock bolt tightened to 30 Nm (22 lb-ft). End this procedure by reinstalling the complete set that includes the rear wheel speed sensor along with the brake disc and differential housing cover.
