What's Included

In the box you’ll find the essential components to rebuild the front differential’s sealing system and restore proper lubrication.

  • Front differential seals
  • Front differential bearings
  • Pinion seals
  • O-rings and associated gaskets

Note: Related parts such as front differential cover gaskets or differential oil are not included.

Why Choose This Aftermarket Replacement?

  • Direct-Fit Compatibility: Precisely matched to the front-diff geometry for a straightforward, bolt-on rebuild.
  • OEM Cross-Reference: Widely cross-referenced with Honda OEM part numbers to ensure accurate replacement parts.
  • Premium Materials: High-grade elastomer seals and robust bearings designed to resist dirt, water ingress, and vibration.
  • Comprehensive Coverage: Includes all bearings and seals required for a complete front-diff rebuild, reducing shopping and downtime.
  • Performance Restoration: Restores reliable oil retention and differential performance after years of use in harsh environments.
  • Value: Cost-effective solution that delivers OEM-grade function without OEM pricing.

Installation Notes:

  • Drain and Clean: Drain differential oil and thoroughly clean the front-diff housing and mating surfaces before install.
  • Inspect Components: Check the pinion shaft, bearings, and gears for wear; replace any damaged parts along with the kit.
  • Lubrication Prep: Lightly coat seal lips with clean differential oil before seating to ease installation and reduce dry-run wear.
  • Seating Seals: Use appropriate seal drivers or a soft mallet to seat seals evenly without bending lips.
  • Correct Orientation: Ensure correct seal orientation and bearing face seating to avoid premature leaks.
  • Torque and Fasteners: Reinstall all bolts to OEM torque specs and verify the front-diff cover and mounting hardware are secure.

Why Upgrade?

Running a worn front-differential seal kit risks ongoing oil loss, contamination, and accelerated gear wear, which can lead to costly drivetrain failure. This replacement restores proper oil retention, protects gears from dirt and water intrusion, and reestablishes reliable performance in demanding trail or farm conditions.
