Front Axle Knuckle Vacuum Seals & Hub O-Rings Kit for Ford Super Duty

Our review of this front axle knuckle tube seal kit finds it best for Ford Super Duty owners who need a direct, no-frills replacement for worn axle seals. It is specifically intended for 2005-2019 F250, F350, F450 and F550 models with Dana Super 60 axles, and the single biggest reason to buy is straightforward compatibility: the kit replaces the common service parts #2017426, #2014835 and #54983 so a mechanic can swap out failed seals with minimal fuss. The kit is a compact, practical repair pack rather than an upgrade, aimed at restoring leak-free operation.

Key Features

• Compatibility: Designed for Ford Super Duty 2005-2019 F250 to F550 with Dana Super 60, ensuring a direct fit when replacing original knuckle and tube seals.
• Complete small kit: Includes 2 inner knuckle seals, 2 outer tube oil seals and 2 vacuum seal O-rings, providing the basic parts needed for most axle knuckle seal jobs.
• Leak prevention: The seals are intended to stop oil leakage and keep water, dirt and sand out of the knuckle assembly, which helps reduce unwanted wear.
• Durable materials: Constructed from steel and rubber rated as corrosion resistant and wear resistant to deliver longer service life than failed or aged seals.
• Simple replacement: The kit is meant to be installed in the original positions after removing old seals, so the replacement process is straightforward for a technician.
• Support and warranty: Offers a 30-day return and 1-year replacement promise with customer support available for damaged or incorrect items.

Who It's For

This kit is for owners and mechanics working on Ford Super Duty trucks with Dana Super 60 axles from model years 2005 through 2019 who need to replace leaking or damaged knuckle and tube seals. It is especially useful for routine axle maintenance, tackling oil leaks, or repairing seals after off-road use that exposed components to water and debris.

It is not aimed at custom axle modification or high-performance sealing upgrades; users seeking improved sealing beyond stock replacement or a full axle overhaul should consider specialty components or a complete rebuild kit instead.
