SKF BR930470 Wheel Bearing and Hub Assembly - Front

SKF BR930470 Front Wheel Hub Assembly

SKF BR930470 is a front wheel bearing and hub assembly built for vehicles that need stable handling, consistent braking response, and precise hub support. It uses SKF’s X-Tracker design with a double-row angular contact ball bearing arrangement to increase bearing capacity and improve hub stiffness.

Compatible with Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, Isuzu Ascender, Buick Rainier, Chevrolet SSR, Trailblazer EXT, Envoy XL, Envoy XUV, and Oldsmobile Bravada front applications, this hub assembly is built around the dimensions and flange geometry needed for a direct-fit repair.

Key Features

• Part number BR930470 for front wheel bearing and hub service
• X-Tracker high-performance hub design for improved handling and braking response
• Double-row angular contact ball bearing construction for increased load capacity
• Hub stiffness increased by 50 percent versus an original tapered bearing hub, per SKF
• Triangular flange shape with precise pilot and offset dimensions for fitment accuracy
• Cross-reference part numbers: 12413037, 8124130370

Detailed Description

SKF BR930470 is engineered as a wheel bearing and hub assembly for front axle service on a wide range of GM and related SUV applications. The X-Tracker platform uses a double-row angular contact ball bearing arrangement to support higher loads while maintaining the rigidity needed for predictable steering and braking. Key dimensions include a 4.987-inch bearing diameter, 1.111-inch inside diameter, 3.062-inch wheel pilot diameter, 3.109-inch brake pilot diameter, 3.281-inch hub pilot diameter, 1.853-inch flange offset, and 5.935-inch flange diameter. The triangular flange shape is part of the assembly’s fitment profile and helps match the original mounting geometry.

This part number BR930470 is a direct-fit option for front wheel bearing replacement on 2002-2009 Chevrolet Trailblazer, front; 2002-2009 GMC Envoy, front; 2005-2009 Saab 9-7x, front; 2003-2008 Isuzu Ascender, front; 2004-2007 Buick Rainier, front; 2003-2006 Chevrolet SSR, front; 2002-2006 Chevrolet Trailblazer EXT, front; 2002-2006 GMC Envoy XL, front; 2004-2005 GMC Envoy XUV, front; and 2002-2004 Oldsmobile Bravada, front.

What This Part Helps Address

• Front wheel bearing noise or roughness
• Excessive hub play or looseness
• Uneven braking feel caused by worn hub support
• Steering instability from a deteriorated front hub assembly
• Vibration or wheel-end wear related to bearing fatigue

Installation Notes and Tips

Confirm the vehicle’s year, make, model, and front position before installation. Verify hub pilot, brake pilot, and flange dimensions against the original part, and inspect related wheel-end components for wear before reassembly. For best results, follow the vehicle manufacturer’s service procedure and torque specifications during installation.
