Spicer Front Axle Spindle Thrust Washer 3-Piece Kit for Ford F-250 & F-350 Super Duty (Dana 50 / 60)

Eliminate excessive outer axle shaft end-play, stop front-end clunking noises, and safeguard your wheel-end assemblies with this genuine Spicer Front Axle Spindle Outer Thrust Washer Kit. Specifically engineered for 1999–2011 Ford F-250, F-350, F-450, and F-550 Super Duty trucks (as well as 2000–2005 Ford Excursion models) equipped with a monobeam Dana 50 or Dana 60 front axle housing, this factory-correct hardware package replaces worn, crushed, or missing spindle spacing components.

On heavy-duty Ford 4x4 platforms, the outer stub axle shaft relies on a precise hardware stack inside the wheel hub to control lateral movement. Located on the outer side of the main hub bearing and locked in by the axle shaft c-clip, these specialized washers manage physical clearances while the truck steers or handles severe off-road axle angles. Over years of heavy hauling, severe trail vibration, or hub locking cycle wear, the center composite spacing washer can crack, flatten, or dissolve entirely. When this spacer fails, the outer stub shaft gains too much lateral play—resulting in harsh metallic clunking or clicking sounds over bumps, accelerated wear on the vacuum knuckle seals, and erratic automated 4WD hub engagement.

This original equipment manufacturer (OEM) kit includes all three exact components necessary to restore mandatory spacing metrics. It contains the matching pair of hardened round steel outer thrust washers alongside the critical multi-sided composite center washer to guarantee structural durability and quiet, friction-free operation under maximum torsional load.
