Spicer Front Outer Axle Stub Shaft, Seal & U-Joint Kit for Ford Super Duty (Dana 50/60, 1999-2004)

Completely overhaul a single side of your truck's front drivetrain with this genuine Spicer Front Outer Axle Stub Shaft, Seal, and U-Joint Kit. Specially bundled for 1999–2004 Ford F-250, F-350, and F-450 Super Duty models equipped with Dana 50 or Dana 60 front axles, this master service kit combines three essential, heavy-duty replacement components into one convenient package.

Heavy towing, commercial operations, and aggressive off-road use place intense stress on your Super Duty's front outer axle assemblies. Over time, the outer stub shaft splines can strip or twist, the factory universal joint can wear dry and bind up, and the critical knuckle vacuum seals can degrade—leading to costly automatic 4WD engagement failures and fluid leaks. This comprehensive kit eliminates the guesswork of sourcing individual parts by replacing those high-wear components with trusted Spicer OEM engineering, restoring original mechanical strength, sealing out trail grit, and returning smooth, predictable rotational performance to your front end.

Kit Highlights:

• Complete Single-Side Overhaul: Bundles one heavy-duty outer axle stub shaft, one premium maintenance-free universal joint, and the critical outer main vacuum knuckle oil seal with matching thrust washers and snap rings.

• Genuine Spicer OEM Quality: Forged from high-grade, fatigue-resistant steel and specialized elastomeric compounds to meet rigid factory dimensions and maximize pure component service life.

• Restores Automated 4WD Performance: Replaces dry or torn factory knuckle hub seals to immediately restore proper vacuum pressure for reliable automatic Pulse Vacuum Hub (PVH) engagement.

• Direct Application Fit: Mapped precisely for leaf-sprung 1999–2004 Ford Super Duty monobeam Dana 50 and Dana 60 front axle configurations.
