Spicer Front Axle Seals & Maintenance-Free U-Joints Kit for Ford F-250 & F-350 (Dana 50/60, 1998-2004, Both Sides)

Eliminate front-end clicking, resolve stubborn vacuum hub leaks, and restore original drivetrain reliability with this genuine Spicer Front Axle Seals and Universal Joint Overhaul Kit. Specially engineered to completely service both the driver and passenger sides of leaf-sprung 1998–2004 Ford F-250 and F-350 Super Duty trucks (and 2000–2005 Ford Excursion models) equipped with a monobeam Dana 50 or Dana 60 front axle, this premium master bundle addresses mechanical wear and vacuum failures simultaneously.

The front outer wheel ends on early Super Duty platforms endure severe load stresses. Over time, dry axle u-joints cause grinding feedback and low-speed steering wheel binding during tight maneuvers, while degraded knuckle seals cause the factory Pulse Vacuum Hub (PVH) system to lose its air-tight isolation. When that vacuum seal fails, automatic dashboard-engaged 4WD stops working completely.

This kit eliminates the hassle of tracking down individual parts by combining premium Spicer Life Series (SPL) non-greasable universal joints with a complete sequence of factory-original seals and o-rings. Upgrading with this master kit re-establishes an airtight pneumatic seal while renewing the rotating strength of your front axle shafts.

Kit Highlights:

• Complete Dual-Side Service Package: Contains 2 genuine Spicer premium non-greasable front axle universal joints, 2 massive main outer knuckle vacuum seals, 2 inner axle tube oil seals, and the supporting wheel hub assembly o-rings.

• Maintenance-Free SPL U-Joints: Built with a solid cross body and multi-lip synthetic rubber seals that permanently lock lubrication inside, keeping trail water, road salt, mud, and grit out.

• Genuine Spicer OEM Quality: Manufactured by the original equipment supplier to strict structural and material tolerances, ensuring far greater longevity than generic aftermarket alternatives.

• Restores Automatic 4x4 Function: Provides the high-precision, multi-lip outer hub vacuum seals necessary to fix air leaks and guarantee error-free automatic 4x4 engagement.
