Differential Bearing Kit Rear For Honda TRX500FA 2015 to 2018 TRX500FE 2014 to 2018 TRX520FM 2020 to 2023

This rear differential bearing kit is designed for the TRX500/520 ATV family produced from 2014 through 2023. It bundles precision bearings and seals to restore smooth rear-end operation, reduce gear noise, and seal out dirt and moisture that can compromise the differential. Compatibility includes multiple TRX500 variants (FA, FE, FM IRS, FM Solid Axle) and the TRX520 FM, helping you complete a drivetrain service quickly and with confidence.

With wear from mud, water, and continuous torque, worn rear-diff components can leak, develop play, and lead to uneven gear engagement. This aftermarket replacement is engineered to restore proper preload, seal integrity, and bearing life, delivering dependable performance for trail rides or farm chores.

Why Choose This Aftermarket Replacement?

• Direct-Fit Compatibility: Precisely matched to the TRX500/520 rear differential bearings and seals for a trouble-free install.
• OEM Cross-Reference: Provides a proven cross-reference path to common OEM part numbers for easier sourcing.
• Premium Materials: High-grade bearing steel and robust seals designed to resist dirt, water, and wear in harsh environments.
• Complete Service Kit: Includes all needed bearings, seals, and retaining rings to complete a single, clean service.
• Performance Restoration: Restores smooth operation, reduces noise, and protects against oil leaks during demanding trail or farm use.
• Cost-Effective Maintenance: A reliable aftermarket option that avoids OEM price premiums while delivering factory-like performance.

Installation Notes:

• Preparation: Remove the old components carefully and inspect bore surfaces for scoring or corrosion before installing the new kit.
• Pressing Bearings: Use a proper bearing press or drift tools; avoid hammering to prevent race or seal damage.
• Seal Orientation: Install seals with the correct lip orientation to maximize sealing effectiveness and prevent leaks.
• Lubrication: Lightly grease seal lips and bearing surfaces before installation to ease seating and prevent abrasion.
• Clean Seating Surfaces: Ensure all seating faces are clean and free of debris; a contaminated bore can reduce bearing life.
• Final Checks: After assembly, rotate the differential by hand to check for smoothness, and verify proper endplay before refilling with gear oil.

Why Upgrade?

Worn rear-differential bearings and seals can allow dirt ingress, cause play and gear misalignment, and lead to oil leaks or eventual differential failure. Upgrading with this kit restores proper tolerances, seals out contaminants, and renews reliable drivetrain performance for both trails and farm work.
