Spicer Front Outer Axle Shaft Seal & U-Joint Kit for 2005-2016 Ford F-450 & F-550 (Dana 60, Single Side)

Eliminate violent front-axle binding, restore your Electronic Locking Hub (ESOF) vacuum sealing system, and overhaul your front wheel ends with this genuine Spicer Front Outer Axle Shaft Seal & U-Joint Master Kit. Specially bundled to service the heavy-duty, wide-track Dana 60 front axle housings found exclusively on 2005–2016 Ford F-450 and F-550 Super Duty trucks, this single-side master package replaces worn universal joints and leaking knuckle vacuum seals.

On commercial-grade Ford 4x4 platforms, the front steering knuckle houses a complex combination of high-torque drivetrain components and vacuum-actuated hub assemblies. Over high mileage, intensive commercial fleet towing, or harsh winter snowplow abuse, the front axle U-joints experience extreme friction and begin to seize, causing a dangerous jerking or binding sensation in the steering wheel when turned. Simultaneously, the large outer yellow hub vacuum seal dry-rots, causing an immediate vacuum drop that disables your dashboard-controlled automatic 4WD engagement system.

This original equipment manufacturer (OEM) master service package supplies everything needed to properly overhaul one complete front steering knuckle station. Sourcing genuine Spicer components guarantees exact original equipment dimensional specifications, matching rubber durometer formulas, and high-strength solid-cross universal joints engineered to handle massive Powerstroke diesel torque without shearing.
