Installation Notes:

• Drain and replace differential oil before reinstalling the front differential components.
• Clean all mating surfaces thoroughly; inspect the ring gear and pinion for wear and replace the pinion bearing only if specified by the kit or service manual.
• Install seals with the correct orientation to maintain proper grease retention and water exclusion.
• Lubricate seals lightly with manufacturer-recommended lubricant or oil before seating to prevent nicking during installation.
• Follow the service manual for torque specs on seals and fasteners; ensure the cover gasket or sealant is properly applied if called for in the procedure.
• Inspect for any play in the front diff after assembly and refill to the correct oil level with the recommended fluid.

Why Upgrade?

Running a worn front-differential bearing and seal setup invites progressive gear wear, oil leaks, and loss of drive efficiency, especially under load on trails or jobs. This aftermarket replacement restores reliable sealing and bearing integrity, helping the front end stay engaged and quiet while protecting the drivetrain from premature failure.
