Spicer Front Outer Axle Stub Shaft Thrust Washer & Snap Ring Hardware Overhaul Kit for 1998-2004 Ford Super Duty (Dana 50 / 60, Both Sides)

Eliminate excessive outer stub shaft end-play, prevent premature wear on your front vacuum seals, and fully restore your 4x4 hub locking assemblies with this genuine Spicer Outer Axle Shaft Thrust Washer & Snap Ring Overhaul Kit. Specifically packaged as a complete, dual-side hardware solution for 1998–2004 Ford F-250 and F-350 Super Duty trucks and 2000–2005 Ford Excursion models, this premium kit includes all the mandatory wheel-end hardware required to service both front steering knuckles at the same time.

On solid-axle Ford platforms, each outer axle stub shaft passes through the steering knuckle and wheel hub unit bearing assembly, locked tightly in place by a heavy-duty snap ring. Positioned immediately behind these snap rings is a critical 3-piece thrust washer configuration consisting of one grooved plastic/nylon spacer flanked by two steel shims. Together, these components lock the axle shaft's outward lateral movement. Over high mileage, heavy towing, or routine front-end maintenance, the plastic thrust washers naturally score, flatten, or break, while the steel snap rings can distort or lose their tension during removal. Failing to replace worn or missing thrust washers introduces excessive shaft "in-and-out" play, which rapidly destroys your expensive inner spindle needle bearings and tears the large rubber vacuum knuckle seals—instantly disabling your dashboard-controlled automatic 4WD engagement system.

This original equipment manufacturer (OEM) small parts master package supplies a factory-correct hardware setup to completely overhaul both the driver and passenger side wheel stations. Sourcing genuine Spicer hardware ensures exact original equipment washer thicknesses, precise outer snap ring dimensions, and specialized materials engineered to withstand the continuous rotational friction of your front axle assemblies.
