Bonbo Front Axle Knuckle & Tube Seal Kit for Ford Super Duty Dana Super 60 (2005-2019) — 6‑Piece Steel/Rubber

This Bonbo seal kit bundles the inner knuckle seals, outer tube oil seals and vacuum O-rings you need to restore a solid front-axle seal on F250, F350, F450 and F550 trucks equipped with a Dana Super 60 axle. Built from corrosion-resistant steel and durable rubber, the parts are intended to reduce friction, keep contaminants out and stop axle fluid leaks when worn original seals are removed and replaced.

What exactly is included and which Ford trucks does this fit?

The kit contains six pieces: two inner knuckle seals (replacing #2017426), two outer tube oil seals (replacing #2014835) and two vacuum seal O-rings (replacing #54983). It was made specifically for Ford Super Duty 2005–2019 models with dual or single rear wheel 4x4 configurations using the Dana Super 60 axle housing.

• 2 x Inner knuckle seals (drop-in replacements for #2017426)
• 2 x Outer tube oil seals (replaces #2014835)
• 2 x Vacuum seal O-rings (replaces #54983)
• Compatible: Ford Super Duty F250/F350/F450/F550, 2005–2019, Dana Super 60

How do these seals improve axle performance on my truck?

New seals restore axle lubrication retention and keep water, dirt and grit from entering the knuckle and tube assemblies. Proper sealing reduces wear on bearings and shafts, helps eliminate noise and vibration related to contamination or fluid loss, and supports predictable steering and hub operation.

• Prevents lubricant leakage and contamination ingress
• Reduces friction and premature component wear
• Improves driving comfort by lowering noise and vibration

Are these parts easy to install — what should I expect during replacement?

Installation follows standard knuckle/tube seal replacement procedures: remove the old, damaged seals and O-rings, clean the mating surfaces, and press the new parts into their original positions. Basic mechanical tools and some experience working with axle assemblies are recommended; if in doubt, consult a repair manual or professional mechanic.

• Remove worn seals carefully to avoid damaging housings
• Clean surfaces before installing new steel/rubber seals
• Use proper tools to seat seals flush and check for leaks after assembly

What are the construction materials and durability expectations?

Bonbo designs these seals using corrosion-resistant steel for structural components and resilient rubber for sealing surfaces to resist deformation and impact. While they are built for long-lasting service, life expectancy depends on driving conditions, load, and maintenance; replace seals as soon as signs of cracking, leaks or abrasion appear.

• Steel reinforcement for shape and corrosion resistance
• Durable rubber lip seals for effective fluid retention
• Designed to resist impact and common road contaminants
