Front Differential Bearing And Seal Kit For Yamaha YFM 350 Grizzly IRS 07 11 YFM 550 Grizzly 07 12 YFM 700 Grizzly 07 12

This Front Differential Bearing And Seal Kit for Yamaha Grizzly models consolidates all the essential bearings and seals you need to rebuild the front differential on YFM350 Grizzly IRS (07–11), YFM550 Grizzly (07–12), and YFM700 Grizzly (07–12). Replacing worn bearings and seals restores quiet, smooth operation and prevents oil leaks that can lead to differential damage in tough off-road conditions. Built for rugged trail and farm use, this kit minimizes downtime and keeps your front drivetrain performing when the going gets muddy or wet.

Designed to tackle the harsh realities of off-road use, this kit uses high-speed EMQ bearings and Type-TC rubber seals with garter springs for superior sealing against water, dirt, and grit. It provides a complete front-diff service in one package, helping you avoid piecing together mismatched parts and delivering reliable, long-lasting performance on the trail or in the field.

Installation Notes:

• Drain and clean—fully drain front-diff oil and clean mating surfaces before reassembly.
• Inspect and measure—check pinion shaft, gear backlash, and seal surfaces for wear; replace as needed.
• Bearing orientation—press bearings straight and square to avoid premature failure; use proper tooling.
• Seal orientation—install seals with correct lip orientation and ensure flat, clean sealing faces.
• Lubrication and grease—use fresh gear oil per Yamaha specifications; lightly grease seals if recommended by the kit instructions.
• Reassembly and torque—torque fasteners to the manufacturer’s service specs and reinstall the differential cover with new gasket/seal if provided.

Why Upgrade?

Running a worn front-diff bearing or degraded seals can lead to leaks, contamination, and eventual differential failure, which compromises steering and traction in demanding conditions. This replacement restores reliable sealing and smooth operation, protecting gears and enabling confident performance across trail and farm tasks.
