Spicer Front Axle Wheel Bearing, Vacuum Seal & Small Parts Master Service Kit for Ford Super Duty (Dana 50/60, 1999-2004)

Restore factory-spec performance, seal out harsh trail elements, and completely rebuild a single side of your truck's front wheel end with this genuine Spicer Front Axle Bearing, Seal, and Small Parts Master Kit. Specially compiled for 1999–2004 Ford F-250 and F-350 Super Duty trucks equipped with Dana 50 or Dana 60 front axles, this complete bundle takes the hassle out of sourcing individual replacement items by pairing vital hub bearings, seals, and specialized hardware into one convenient package.

Heavy commercial hauling, heavy towing, mud, and road debris subject the front steering knuckles and hubs of these trucks to tremendous physical strain. Over time, internal spindle needle bearings dry up and pit, while the main outer vacuum hub seals degrade—resulting in automatic four-wheel-drive failures (Pulse Vacuum Hub system leaks) and harsh metallic grinding noises at the wheels. This master hardware kit swaps out those failing components with trusted Spicer OEM parts, ensuring an airtight vacuum seal, proper rotational tolerances, and total protection against moisture and grit entering your internal axle tubes.

Kit Highlights:

• Complete Single-Side Master Rebuild: Packages the critical front spindle needle bearing, the main outer knuckle vacuum hub seal, specialized thrust washers, snap rings, and dust guides needed to fully service one side.

• Genuine Spicer OEM Quality: Engineered to rigorous original factory dimensions using premium-grade steel and advanced elastomeric compounds to maximize fatigue resistance and service life.

• Fixes Automatic 4WD Failures: Replaces worn or torn knuckle hub seals to immediately restore the necessary vacuum pressure for reliable factory automatic 4WD engagement.

• Direct Application Fitment: Specially mapped for leaf-sprung 1999–2004 Ford Super Duty monobeam Dana 50 and Dana 60 front axle configurations.
