MOOSE OFFROAD YAM-7040 Rear CV Axle — Yamaha Wolverine X2 850 / X4 (2018-2019)

MOOSE OFFROAD — Chromoly Steel Strength, Precision Heat-Treated Performance, and Rugged OEM-Plus Reliability for the Wolverine 850

Restore the power delivery of your machine with the MOOSE OFFROAD YAM-7040 OEM Replacement Standard CV Axle. Engineered specifically for the early-generation Yamaha Wolverine X2 and X4 850 platforms (2018-2019), this complete axle assembly is the definitive upgrade over stock hardware. Whether you are navigating tight technical trails or hauling cargo through the backcountry, these axles are built to handle high-torque loads and extreme angles without the risk of binding or premature joint failure.

Every MOOSE OFFROAD axle is manufactured in an ISO9001 and TS16949 certified facility, utilizing a solid chromoly steel center shaft that is tested to be up to 35% stronger than standard OEM components. The internal cages, races, and ball bearings undergo induction heat treatment for maximum wear resistance and are pre-packed with high-performance moly grease to reduce friction and heat buildup. This axle arrives fully assembled and ready for a "drop-in" installation, featuring precision-rolled splines for a perfect hub fit and secure stainless steel clamps to keep the dust boots sealed against mud and water ingress.

• High-Strength Chromoly: Precision-machined solid chromoly steel center shaft provides superior durability over stock axles.
• Induction Heat-Treated Joints: Packed with premium moly grease to withstand the most rigorous trail conditions and terrain.
• ISO9001 Certified: Manufactured to strict quality standards to ensure fit, form, and function exceed OEM quality.
• Easy Installation: Fully assembled kit including high-strength spring steel retaining clips for a seamless bolt-on experience.
• Universal Rear Fitment: Designed to fit both the Rear Left and Rear Right positions on the Wolverine 850 chassis.
• Secure Boot Protection: High-quality boots secured with stainless steel clamps to protect the CV joint from the elements.

Moto-House MX Pro Tip:

The 2018-2019 Wolverine X2 and X4 were the pioneers of the 850 platform, and their rear axles are the primary link for getting power to the ground. If you notice a torn rubber boot or hear a rhythmic "clicking" while accelerating, replace the axle immediately before it shears and leaves you stranded. When installing the MOOSE OFFROAD YAM-7040, we recommend applying a thin layer of waterproof grease to the splines to prevent the axle from seizing in the hub over time. Note: Always torque your axle nut to the factory-specified setting and use a fresh cotter pin for safety.
