A Ford 8.8 In Rear Differential service and repair of its
Axle Shaft must start by lifting and securing your vehicle then removing the wheel assembly along with the tire. The lubricant must drain into a clean container before you can remove the differential housing cover by unfastening its 10 bolts. Vehicle owners should first remove the rear brake drums on vehicles with drum brakes or detach the rear disc
Brake Caliper and secure it with a wire to gain access to the rear
Brake Disc. The differential pinion shaft removal begins with discarding the lock bolt before the shaft extraction process. When removing U-washers and two axle shafts from the grooves maintain care to protect the rubber O-rings. Before mounting the wheel bearing oil seal grease the lip then put in the two axle shafts while protecting the U-washer rubber O-ring grooves from harm. Fix the U-washer to the button area of each axle shaft then stretch the axle outward. Installation of the differential pinion shaft requires new lock bolts unless otherwise unavailable where the threads should receive a threadlock application before alignment through the case lock bolt hole to secure with new lock bolts. The rear brake drums must be reinstalled when the vehicle has drum brakes while disc brake vehicles require installation of the rear brake disc and caliper. Install a continuous new bead of sealant to the cover before sealing the differential housing. New sealant use is unnecessary when the cover installation occurs within 15 minutes. The specified lubricant quantity should be filled into the rear axle housing until it reaches 2.37 liters (5 pints). The last step involves cleaning all foreign matter and corrosion from wheel mounting areas to establish proper metal surface contact before wheel and tire installation.
