JAVIK Polaris front hub and strut bearing & seal kit — complete OEM-fit rebuild (bearings, seals, O-rings)

Complete front hub, strut bearings and seal kit designed to replace worn Polaris OEM parts and restore stable front-wheel performance.

This JAVIK replacement kit bundles all the bearings, cups, seals and O-rings needed to service the front hub and strut assemblies on many Polaris ATV and UTV models from the mid-1990s through the 2000s. Supplied parts match the OEM reference numbers listed by Polaris (3610028, 3554509, 3554507, 3610019, 3554506) so you can swap components without improvising fitment. The package includes taper roller bearings, roll cups, hub and strut seals plus O-rings to cover a full front-wheel overhaul.

Which Polaris models and years will this kit fit?

This kit is compatible with a wide range of Polaris vehicles—covering Scrambler, Sportsman, Magnum, Ranger, Xpedition, Xplorer, Big Boss, Diesel and Worker series across specific years and configurations. Always verify the OEM part numbers on your machine against the list included here before ordering.

• Examples: Sportsman 400 (1995–2004), Scrambler 500 4x4 (1997–2009), Magnum 325 (2000–2002)
• Includes fitment for select 4x4/6x6 and many non-2x4 variants
• See OEM references: 3610028, 3554509, 3554507, 3610019, 3554506

What parts are included in the JAVIK kit and why each matters?

The kit is packaged to replace both hub and strut related components so you get matched bearings and seals for a consistent rebuild. Matched components reduce installation guesswork and help maintain correct bearing preload and seal integrity after service.

• 3610028: Strut seals x2 — prevent grease loss and contamination
• 3610019: Hub seals x2 — protect hub bearings from dirt and water
• 3554509, 3554506: Taper roller bearings x4 total — handle radial and axial loads
• 3554507: Taper roll cups x4 — race surfaces for the bearings
• 5410470: O-rings x2 — ensure correct sealing at mating components

How will replacing these bearings and seals affect ride and maintenance?

Installing new bearings and seals typically reduces wheel play, removes grinding or rumbling from the front end, and stops grease leaks that attract dirt. That results in steadier steering feel and can extend the life of related steering and suspension parts when installed properly.

• Reduces front-wheel vibration and looseness when worn parts are replaced
• Stops contaminants from accelerating bearing wear
• Allows correct bearing adjustment during reassembly for longer service life

What should I check before buying and during installation?

Confirm your ATV/UTV model and year against the fitment list, and cross-check the OEM numbers stamped on existing parts. During installation inspect hubs, spindle threads, seals seats, and spindle nuts for damage; replace any additional worn hardware to avoid premature failure.

• Verify the OEM numbers on your current bearings/seals match those listed
• Inspect hub bores and spindle surfaces for scoring or corrosion
• Use correct torque and bearing preload procedures on reassembly

Who is this for: This JAVIK kit is intended for owners, mechanics and restoration enthusiasts working on Polaris ATVs and UTVs listed in the fitment table who need a complete front hub and strut bearing refresh. If you are tackling a front-end rebuild, addressing noise, looseness, or leaks, or preparing a vehicle for heavy use, this set provides the matched components required for correct replacement. Note: always confirm fitment and, if unsure about installation, consult a certified technician or service manual for your specific Polaris model.
