Spicer Front Axle U-Joint, Vacuum Knuckle & Tube Seal Overhaul Kit for 2005-2014 Ford Super Duty (Dana Super 60, Single Side)

Eliminate harsh front-end driveline vibrations, restore your automatic four-wheel-drive engagement, and protect your wheel ends from trail debris with this genuine Spicer Front Axle Seal & U-Joint Overhaul Kit. Specifically packaged as a focused, single-side maintenance solution for 2005–2014 Ford F-250 and F-350 Super Duty 4x4 trucks, this premium hardware bundle includes the primary rotating components and multi-lip seals required to refresh either the driver or passenger side of your front axle.

On coil-spring Ford Super Duty platforms, the front Dana Super 60 solid axle endures incredible structural and rotational strain under the immense weight of the 6.0L, 6.4L, or 6.7L PowerStroke Turbo Diesel engines. Over time, the front axle shaft universal joints naturally dry out, flat-spot, or suffer moisture intrusion. A binding or dry U-joint causes severe steering wheel feedback, tire scrubbing, and accelerated hub unit bearing wear—and left unchecked, it can snap entirely, taking out your expensive inner and outer axle shafts. Simultaneously, the massive primary knuckle vacuum seals integrated into this assembly can dry-rot or tear. When these fail, your Electronic Shift-on-the-Fly (ESOF) system loses vacuum pressure, instantly disabling your dashboard-controlled automatic 4WD.

This original equipment manufacturer (OEM) service package eliminates the hassle of sourcing individual components by pairing a premium Spicer Life Series (SPL) non-greaseable universal joint with the factory-correct primary vacuum knuckle seal and an updated outer axle tube dust seal. The included dust seal presses into the end of the housing tube to block water, road salt, and mud from migrating down the tube toward your inner differential seals. Sourcing a genuine Spicer service bundle ensures exact original equipment tolerances, uncompromised metallurgy, and matching factory blueprints for a seamless, long-lasting repair.
