    Q:
    How to service the axle shaft of a 9.75 Inch Rear Differential on Ford F-150 Heritage? Posted by Customer
    A:
    The first step to serve the Ford 9.75 Inch Rear Differential axle shaft requires powering off the air suspension system using the air suspension switch inside the RH kick panel area to avoid unexpected pressure changes in air springs. Start by lifting the vehicle and supporting it before removing wound components that consist of tire assemblies with their differential housing cover for draining lubricant. After brake caliper disc removal follow the process of shaft differential pinion extraction by discarding its lock bolt and extracting the shaft. After pulling the axle shafts toward the inner position avoid injuring any rubber O-ring material within the axle shaft grooves. Extract the two axle shafts by following a precise method to prevent damage to the wheel bearing oil seal. When installing the two axle shafts apply Premium Long-Life Grease XG-1-C or an equivalent to the lip of the wheel bearing oil seal that meets Ford specification ESA-MIC75-B. Install the axle shafts while ensuring the seal stays unaffected. Insert each U-washer onto its respective axle shaft button and extend the shaft. You must apply Threadlock and Sealer EOAZ-19554-AA or an equivalent material that satisfies Ford specifications WSK-M2G35I-A5 to the lock bolt threads when you cannot use a new pinion shaft lock bolt. Then position the differential pinion shaft to mate with the case lock bolt hole before tightening a new lock bolt. The brake discs can be reinstalled with the differential housing cover followed by filling the specified rear axle housing lubrication and completing tire and wheel reattachment.
