Front Differential Bearing Seal Kit For Honda TRX500 FA 2015-2018 FE 2014-2018 FM IRS 2015-2018 Solid Axle FM 2014-2018

This Front Differential Bearing Seal Kit is a complete aftermarket replacement designed specifically for the TRX500 IRS family and its front differential. It restores the sealing surface and bearing interface to keep gear oil contained and contaminants out, so you’re not losing lubrication on rough trails or demanding farm work. The kit is sized for the 2015-era TRX500 IRS machines across the Foreman Rubicon and related ES/Solid Axle variants, delivering a reliable, ready-to-install fix without OEM pricing. Replacing worn seals now prevents leaks and costly drivetrain damage down the line.

This aftermarket solution delivers tangible value where it counts—reliable sealing under mud, water, and dust, plus a convenient, all-in-one service kit that minimizes downtime. It targets common wear patterns in front-diff seals: hardened lips, split O-rings, and corroded grooves that allow oil to escape and debris to intrude. For trail and farm use, opting for a dedicated front-diff seal kit built for the TRX500 IRS ensures long-lasting lubrication, easier maintenance, and peace of mind in demanding conditions.

Installation Notes:

• Drain the front-diff oil and clean the differential housing and mating surfaces thoroughly before removal of the old seals.
• Inspect the seal grooves and bearing surfaces for grooves, pitting, or corrosion; replace any damaged components to prevent re-leaks.
• Lubricate the new seals’ lips with clean gear oil or assembly lube prior to installation; press seals squarely using a proper seal driver to avoid lip damage.
• Install the 22x48x11 seals in the correct orientation (lip facing toward the oil) and seat the 52x72x9 seal flush with the housing face.
• Replace O-rings with new ones and apply a light coat of gear oil to seat them without twisting or pinching.
• Reassemble the diff cover and torque mounting bolts to OEM specifications; refill with the manufacturer’s recommended gear oil and check for leaks after 10–15 minutes of operation.

Why Upgrade?

Running a worn or damaged front-diff seal allows oil to escape and contaminants to enter, accelerating gear wear and reducing lubrication where it matters most. Upgrading to this dedicated front-diff seal kit restores proper sealing and lubrication, improving reliability in tough off-road and farm conditions and helping prevent costly drivetrain failures.
