SKF BR931000 Wheel Bearing and Hub Assembly - Front

SKF Front Wheel Hub Assembly BR931000

SKF BR931000 is a front wheel bearing and hub assembly built for heavy-duty GM truck and SUV applications. It uses an asymmetrical X-Tracker Hybrid bearing design that combines tapered roller bearings on the inboard side with ball bearings on the outboard side for balanced braking response, handling, and steering accuracy.

Compatible with select Chevrolet Silverado, GMC Sierra, Hummer H2, Avalanche 2500, Suburban 2500, and Yukon XL 2500 front applications, this SKF hub assembly is engineered for vehicles that use an 8-bolt hub or X-Tracker Hybrid configuration. Part number BR931000 is also referenced by interchange number 15064670.

Product Details

SKF developed the X-Tracker Hybrid hub line for demanding front-end service where bearing design affects road feel and control. BR931000 uses a hybrid bearing layout to combine the load-carrying characteristics of tapered roller bearings with the rolling efficiency of ball bearings. That design is well suited to front hub service on Chevrolet Silverado 1500, Silverado 2500 HD, GMC Sierra 1500, Sierra 2500 HD, and related heavy-duty platforms from 1999-2007.

This part number, BR931000, is a direct fit for multiple front hub applications across the Chevrolet Silverado and GMC Sierra families, including Hummer H2 and several 2500-series SUV and pickup models. SKF products are manufactured to high quality standards and backed by more than a century of engineering experience in driveline and wheel-end components.

This part cross-references Monroe Shocks & Struts (e.g., 15064670) for the same application.

Common Problems This Part Addresses

• Front wheel bearing noise or roughness
• Excessive play in the front hub assembly
• Steering wander or reduced steering precision
• Brake feel changes related to worn hub support
• Vibration or instability from a worn front wheel bearing and hub assembly

Installation Notes and Tips

Verify the vehicle’s hub configuration, including 8-bolt hub or X-Tracker Hybrid notes, before ordering. Confirm flange dimensions, pilot diameters, and front position fitment against the original part. For Chevrolet Silverado 1500, GMC Sierra 2500 HD, and Hummer H2 front hub service, compare the existing hub assembly to the listed measurements to ensure correct application.

Inspect related wheel-end components during installation, including the knuckle, axle interface, and brake mounting surfaces. Proper torque procedures and clean mating surfaces are important for accurate hub seating and long-term service life.

Quality Assurance

SKF has supplied wheel-end and driveline components for over 100 years, and BR931000 is manufactured to SKF quality standards for long service life and safety-focused performance.
