Spicer Front Axle Master Sealing Kit for Ford F-250 & F-350 Super Duty (Dana 60, 1999-2004)

Completely seal your front-end drivetrain and restore your truck's factory automatic four-wheel-drive system with this premium, genuine Spicer Front Axle Master Sealing Kit. Specially compiled for 1999–2004 Ford F-250 and F-350 Super Duty trucks equipped with a monobeam Dana 60 front axle, this comprehensive service package bundles all the critical high-wear outer seals required to refresh a single side of your front axle assembly.

Heavy commercial use, fleet hauling, mud, and road debris subject your Super Duty's steering knuckles and outer hub assemblies to extreme conditions. Over time, the main vacuum seal (knuckle seal) and the outer dust seals degrade. This causes vacuum leaks that prevent your automatic Pulse Vacuum Hubs (PVH) from locking into place, while simultaneously allowing water and grit to creep into your axle tubes. This master kit eliminates the guesswork of sourcing individual parts by replacing those worn components with trusted Spicer OEM engineering—ensuring an airtight vacuum lock, protecting your internal needle bearings, and keeping fluid contamination at bay.

Kit Highlights:

• Complete Single-Side Master Kit: Packages the large outer knuckle vacuum oil seal, the outer axle tube dust seal, vacuum o-rings, thrust washers, and snap rings needed to service one side.

• Genuine Spicer OEM Quality: Precision-molded from high-grade elastomeric compounds to endure severe operating temperatures, resist tearing, and maximize overall component service life.

• Fixes Common 4WD Engagement Issues: Replaces dry, cracked factory hub seals to instantly restore proper vacuum pressure for reliable automatic 4WD hub functionality.

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