How to service the 9.75 Inch Rear Differential axle shaft on 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.

How to service and repair the 8.8-inch rear differential on Ford Ranger?

The Ford 8.8-inch rear differential requires repair and maintenance after vehicle lifting and wheel support followed by tire removal. Drain the lubricant after removing the brake drum (1126) as well as the differential housing cover (4033). You must discard the bolt and extract the shaft of the differential pinion (4211). When removing the U-washer (4N237) through the rubber O-ring (4A332) groove of the U-washer you should avoid pushing the axle shaft (4234) towards the inside of the assembly. Perform the extraction of the axle shaft while you keep the wheel bearing oil seal (1177) from any kind of damage. The wheel bearing oil seal requires greasing before installation while positioning the U-washer on the axle shaft button end and extending the axle shaft outward but avoiding damage to the rubber O-ring in the U-washer groove. The existing bolt should have its threads coated with threadlock as an alternative to obtaining a new bolt when installing the differential pinion shaft by positioning the bolt hole on the shaft to match the case and tightening it with the new bolt. After filling the differential housing with proper lubricant one should install the brake drum and differential housing cover and put on the rear wheel and tire assembly while lowering the vehicle.

Ford Differential

If you own Ford and want to keep it in top shape, choosing OEM Differential is a smart move. They are precisely engineered and follow strict factory standards. They are made in advanced facilities that use cutting edge technology. Each part goes through thorough testing to confirm strength and safety, so you can trust it. FordPartsDeal.com gives you genuine Ford Differential at some of the affordable online prices without cutting quality. Every OEM Ford part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Ford Differential allows left and right wheels to freely turn whilst maintaining power flow. Ford began with the radical concept of assembly line by Henry and continues to drive production at a pace beyond its competitors, evidence that it is always moving and this is in its DNA. Ford expects to bring together brains and brawn by EcoBoost engines powered by turbos that provide powerful acceleration with lighter fuel bills that will allow families to save a dime. Ford has SYNC loaded in such a way that teenagers scream a song request or a route and the cabin complies without interrupting, eliminating distraction and minimizing driver distraction. Ford includes Co-Pilot360 and even fully electric pickups to demonstrate that safety and emissions can go together, making big claims with actual hardware. Differential in the drive train separates torque across the wheels, allowing each to choose its own speed on the corner and eliminates tire squeal and fight at the wheel. Open Differential provides an equal twist to both directions and that is smooth until one of the tires loses grip, a compromise that is in favor of simplicity. Limited slip Differential adds torque to the slipping wheel, propelling the grip-remaining wheel, sharpening handling and increasing traction on loose gravel or rain. By checking fluids frequently and audibly hearing knocks, drivers do not cause the Differential to fail after thousands of hard miles but create large repair bills and wasted time.
