How to service the 9.75 Inch Rear Differential axle shaft on 2003 Ford F-150?

Begin service of the Ford 9.75 Inch Rear Differential axle shaft only after turning off the air suspension power through the switch in the RH kick panel area to avoid unintended air spring inflation or deflation. First securely elevate the vehicle before taking out wheels and tires and differential housing cover. Extract the lubricating fluid before uninstalling the brake calipers and the discs. To continue the disassembly process remove the differential pinion shaft by breaking its lock bolt free before pulling out the shaft. When removing the U-washers through axle shaft pushing ensure that the rubber O-rings in the axle shaft grooves remain intact. It is crucial to extract the two axle shafts with extreme caution to avoid damaging the wheel bearing oil seal. Apply Premium Long-Life Grease XG-1-C or an equivalent approved by Ford specification ESA-M1C75-B on the oil seal lip for installation purposes. Position the two axle shafts while avoiding O-ring damage in U-washer grooves before placing U-washers on shaft buttons before external shaft extraction. Threadlock and Sealer EOAZ-19554-AA or equivalent WSK-M2G351-A5 material from Ford specifications must be applied to new pinion shaft lock bolt threads before differential pinion shaft installation by positioning the shaft hole over the case lock bolt hole and securing it with a new lock bolt. After refitting the brake discs it is necessary to install the differential housing cover and apply the specified lubricant into the rear axle housing followed by wheel and tire installation before allowing the vehicle to lower.
