Detailed Description

National M86649 is a taper bearing cone used in transfer case output shaft bearing applications and other drivetrain assemblies that require the same dimensions. The bearing is manufactured from premium-grade steel and features crowned raceways and rollers to help distribute load evenly across the contact surfaces. That construction supports consistent operation in applications such as Mercedes-Benz G550 front outer, Hyundai Santa Fe rear outer, Chevrolet Camaro rear outer, and Ford Ranger front outer fitments listed in the catalog.

This part cross-references FM86649 and Y86649 for the same application. Use the part number M86649 when verifying catalog match, and confirm the bearing dimensions, position, and axle or transmission notes before installation.

What It Helps Address

• Noise from a worn or rough transfer case output shaft bearing
• Excessive play at the bearing location
• Heat and wear caused by damaged rollers or raceways
• Drivetrain vibration related to bearing deterioration
• Service replacement for specified front outer and rear outer applications

Installation Notes and Tips

Verify the cone bore, cone length, and cone radius against the original bearing before installation. Match the vehicle year, make, model, and position exactly, since this bearing is used in multiple drivetrain locations including front outer, rear outer, front, rear, and rear inner applications. Clean the housing and inspect the mating race, shaft, and seals for wear before assembly. Proper bearing preload and lubrication are important for long service life.
