Front Axle Vacuum Knuckle Seal Kit with U-Joints for Ford Super Duty

In this review of the Front Axle Vacuum Knuckle Seal Kit with Driveshaft U-Joint, the bottom line is simple: this package is aimed at technicians and hands-on owners rebuilding the front Dana 60 axle on Ford Super Duty trucks from 2005 to 2019. Its single biggest reason to buy is the combined repair approach - seals, O-rings and driveshaft u-joints come together so a front-axle rebuild can be completed without sourcing multiple parts. The review finds the kit useful where fit is correct and the materials are robust for road duty.

Key Features

• Application compatibility: Designed specifically for Ford Super Duty F250, F350, F450 and F550 trucks with front Dana 60 axles made 2005 to 2019, so buyers can match the kit to their vehicle with confidence.
• Complete kit: Includes inner knuckle oil seals, outer tube dust seals, vacuum O-rings, two driveshaft u-joints and clips, which saves time compared with ordering parts individually.
• Seal protection: The tube and knuckle seals prevent dirt intrusion on the outer axle shaft, helping preserve bearings and hub assemblies over time.
• Construction: Made from steel and rubber with high-temperature resistance and anti-corrosion treatment for durability in harsh conditions.
• Direct replacement numbers: Replaces common part numbers such as 2017426 and 2014835, helping users cross-reference during repairs.

Who It's For

This kit is best for mechanics and experienced DIYers who are rebuilding the front axle or servicing the driveshaft on Ford Super Duty trucks with a Dana 60 front axle from 2005 to 2019. It suits shops that want a single kit to handle both seals and u-joint replacement and owners performing a coordinated service to reduce downtime.

Those who should look elsewhere include owners with Dana 50 or non-Dana front axles and anyone unsure about measuring u-joints; the kit's u-joint caps are 1.062 in diameter with a 3.219 in cap-to-cap span, and some customers reported size mismatches requiring different parts or tools.

Pros & Cons
