Why Choose This Aftermarket Replacement?

• Direct-Fit Compatibility with Polaris Hawkeye 4x4 and Ranger front-diff configurations listed in the fitment table.
• OEM Cross-Reference provides reliable cross-checks to widely used Polaris part numbers for seamless dealership-style replacement.
• Premium Materials for bearings and seals designed to withstand mud, water intrusion, and heavy loads typical of trails and farm work.
• Performance Restoration restores proper preload and seal integrity, reducing play, leaks, and differential noise.
• Cost-Effective Alternative to OEM parts while maintaining OEM-level fit and function.
• Proven Durability engineered for demanding off-road use, supporting longer service intervals between rebuilds.

Installation Notes:

• Drain the front differential oil and clean the housing surfaces before disassembly to prevent contamination.
• Inspect the pinion gear and housing for wear; replace any damaged components to prevent premature failure.
• Use proper bearing installation tools to seat new bearings evenly without edge damage; avoid hammering bearings directly.
• Replace all seals with the supplied OEM-style or matched elastomer seals; ensure correct orientation of seals to promote leak resistance.
• Lubricate bearings with appropriate assembly lube before final installation and torque all fasteners to Polaris service specs.
• Refill the differential with the correct type and amount of oil per the service manual, then check for leaks after a short test run.

Why Upgrade?

Running a worn front-differential bearing or degraded seals risks increased play, oil leaks, and accelerated gear wear, which can lead to differential failure and compromised traction in demanding terrain. This kit restores proper preload and sealing, re-establishing reliable engagement and protection against dirt and water ingress for confident trail and farm performance.
