Differential Bearing Seal Kit For Honda TRX 500FE FM FPE FP Rear 2012 2013 ATV Axle

This differential bearing seal kit is a complete rear-differential rebuild solution designed specifically for Honda TRX500 models (FE, FM, FPE/FP) built for 2012 and 2013. It delivers all the bearings and seals needed to restore proper lubrication, seal integrity, and gear engagement in the TRX500’s differential housing. Replacing worn bearings and seals eliminates leaks, reduces gear noise, and rejuvenates low-speed response and overall driveline reliability for trail rides or harsh farm work.

Engineered as an aftermarket replacement, this kit prioritizes rugged durability and straightforward, click-fit installation. It targets the common wear points in the rear differential—rotational play, seal leaks, and dirt ingress—so you stay on the gas instead of chasing leaks. For trail riders and farming setups where downtime hurts, this kit offers a robust, cost-effective path back to dependable 4x4 performance.

Product Specifications

OEM & Aftermarket Cross-Reference Information

What's Included

The box includes the essential components to rebuild the rear differential for the TRX500 series:

• 3 x ball bearings
• 1 x needle bearing
• 3 x seals
• 2 x cir clips

Related parts not included: differential cover gasket, pinion repair sleeve, or other ancillary components unless listed in a separate kit.

Why Choose This Aftermarket Replacement?

• Direct-Fit Compatibility – designed to match Honda TRX500 rear differential geometry for 2012-2013 models, simplifying installation and reducing guesswork.
• – aligns with widely used aftermarket references (e.g., 25-2079-5 / 25-2079-7) to ensure dependable substitution when OEM parts are scarce.
• Premium Materials – high-speed ABEC3-grade bearings and robust double-lip seals provide durable sealing and reduced drag in dirty, wet conditions.
• Sealing & Protection – double-lip seals help keep grease in and contaminants out, extending differential life in mud, water, and dust.
• Performance Restoration – replaces worn components to restore smooth gear engagement, minimize backlash, and improve overall driveline reliability.

Installation Notes:

• Drain differential oil and clean the housing surfaces before disassembly to prevent contamination during reassembly.
• Use a proper bearing press and protective tooling to install bearings squarely without damaging housings or races.
• Orient seals with the lip facing outward to maximize dirt exclusion; apply a light coat of assembly lube on bearings before seating.
• Replace cir clips with new ones to ensure secure retention of internal components; inspect grooves for wear and replace if needed.
• Verify correct bearing and seal sizes for your sub-model; if in doubt, consult the service manual for TRX500 rear-diff specifications.
• Refill with the manufacturer-recommended differential oil and perform a basic leak test after assembly before road testing.

Why Upgrade?

Running a worn rear-differential bearing and seal kit can lead to progressive leaks, gear misalignment, and accelerated wear on the ring and pinion. Replacing with this aftermarket kit restores lubrication retention, reduces noise, and renews confidence in wet, muddy, or dusty conditions, keeping you moving reliably on the trail or the farm.
