Spicer Front Outer Axle Stub Shaft, U-Joint & Seal Master Overhaul Kit for 1998-2004 Ford Super Duty (Dana 60, Both Sides)

Eliminate violent front-end wheel vibrations, restore your automatic four-wheel-drive engagement, and completely rebuild your outer wheel ends with this genuine Spicer Dana 60 Master Overhaul Kit. Specifically packaged as an all-in-one, dual-side restoration solution for 1998–2004 Ford F-250 and F-350 Super Duty 4x4 trucks and 2000–2005 Ford Excursion models, this premium master package includes all the primary rotating axle hardware and multi-lip vacuum seals required to refresh both the driver and passenger sides of your front axle at the same time.

On leaf-spring Ford Super Duty platforms, the front Dana 60 solid axle endures incredible structural and rotational strain under the immense weight of the 7.3L or 6.0L PowerStroke Turbo Diesel engines. Over decades of heavy commercial towing, snowplowing, or trail riding with oversized tires, the outer steel stub shafts (yoke shafts) naturally fatigue. Common failure points include twisted outer splines, deep rust pitting on the hub-seal journal, or ovaled-out universal joint ears caused by a binding front U-joint. Left unchecked, a dry or failing U-joint causes severe steering wheel feedback, tire scrubbing, and can eventually snap completely—destroying your outer wheel end assembly. Simultaneously, the massive primary knuckle vacuum seals integrated into this platform dry-rot or tear over time. When these blow out, your Electronic Shift-on-the-Fly (ESOF) system loses vacuum pressure, leaving your dashboard-controlled automatic 4WD completely inoperable.

This original equipment manufacturer (OEM) master overhaul package eliminates the hassle of tracking down individual components by combining two rugged 30-spline outer stub shafts with premium Spicer heavy-duty universal joints. These universal joints feature cold-forged steel crosses and advanced multi-lip synthetic rubber seals to permanently lock out trail mud, water, and sand. The kit also includes the factory-correct primary vacuum knuckle seals and updated outer axle tube dust seals to re-establish an absolute, airtight fluid and debris barrier. Sourcing a genuine Spicer master bundle ensures exact original equipment tolerances, uncompromised metallurgy, and matching factory blueprints for a seamless, long-lasting repair.
