Spicer Front Axle Outer Vacuum Seal & Greasable U-Joint Overhaul Kit for Ford F-250 & F-350 (Dana Super 60, 2005-2014, Single Side)

Eliminate harsh front-end popping sounds, fix automatic 4WD engagement failures, and refresh your wheel-end wear items with this genuine Spicer Front Axle Outer Vacuum Seal and Greasable U-Joint Overhaul Kit. Carefully curated to service a single side (fits left or right) of coil-sprung 2005–2014 Ford F-250 and F-350 Super Duty (4WD) trucks, this premium maintenance package delivers original equipment quality without the unnecessary cost of replacing still-usable factory steel axle shafts.

The front universal joints and steering knuckle seals on heavy-duty Super Duty trucks bear the brunt of massive diesel engine torque, heavy towing loads, and harsh winter road salt. Over time, original factory u-joints dry out and seize up, creating dangerous binding in the steering wheel during tight maneuvers. Simultaneously, the main multi-lip knuckle seals decay, causing critical vacuum leaks that completely disable your dashboard-operated Pulse Vacuum Hub (PVH) automatic 4x4 engagement. This service-ready bundle completely resolves both problems at once by pairing a premium Spicer greasable universal joint with the required high-performance pneumatic seals. Upgrading to the greasable u-joint design features an integrated zerk fitting, allowing you to easily purge water, mud, and debris during routine oil changes to maximize drivetrain longevity.

Kit Highlights:

• Targeted Single-Side Maintenance: Packages 1 premium greasable front universal joint, 1 massive main outer knuckle vacuum seal, and the auxiliary hub assembly o-ring to fully overhaul one steering knuckle assembly.

• Greasable Drivetrain Upgrade: Features a rugged universal joint equipped with an integrated flush-mount lubrication fitting, facilitating fast preventative maintenance to protect against water intrusion.

• Genuine Spicer OEM Quality: Engineered to exact original equipment structural and dimensional tolerances, guaranteeing a reliable mechanical press-fit and a lasting pneumatic seal.

• Restores Factory Automatic 4WD: Replaces the critical, multi-lip outer hub vacuum seal to re-establish the strict air pressure retention required for error-free automatic front hub locking.
