Timken SP580311 Wheel Bearing and Hub Assembly - Front

Timken SP580311 Wheel Bearing Hub Assembly

Timken SP580311 is a front wheel bearing and hub assembly built for heavy-duty driveline service. It is engineered for 2001-2006 Chevrolet Silverado 3500 and GMC Sierra 3500 front applications, with 2007 Silverado 3500 Classic and Sierra 3500 Classic coverage for dual rear wheel configurations.

Key Features

• OE-developed testing is used to control design, materials, and manufacturing process consistency.
• Low runout helps reduce wheel-end noise and vibration while supporting stable braking performance.
• Premium seals use a reinforced outer case, ribbed rubber inner diameter, contamination exclusion features, and vent holes to support sealing durability.
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes are used to improve load carrying capacity and bearing life.
• Integrated ABS sensor is 100% tested to monitor wheel speed for Anti-lock Braking Systems.
• Driven hub design with 33 splines, 8 wheel studs, and a 6.500-inch bolt circle diameter.

Detailed Description

Timken SP580311 is a driven front hub assembly for Chevrolet Silverado 3500 and GMC Sierra 3500 trucks that need a direct-fit wheel-end service part. The assembly uses a 4-bolt flange, 7.846-inch flange diameter, 2.297-inch flange offset, 4.167-inch hub pilot diameter, 4.594-inch wheel pilot diameter, and 4.641-inch brake pilot diameter. These dimensions support accurate wheel and brake alignment on the specified front axle applications. This part cross-references SKF BR930667 for the same application.

What It Helps Address

• Front wheel bearing noise on Silverado 3500 and Sierra 3500 trucks
• Wheel-end vibration caused by excessive runout
• ABS warning concerns related to wheel speed signal issues
• Brake feel changes linked to hub or bearing wear
• Loose or inconsistent wheel mounting at the front hub

Installation Notes and Tips

Verify front-axle fitment by year, model, and dual rear wheel configuration before installation. Confirm the 33-spline driven hub design, 8-stud wheel pattern, and 6.500-inch bolt circle match the vehicle specification. Inspect the mating surfaces, axle interface, and brake components for wear or damage before installing the new hub assembly. For 2007 Chevrolet Silverado 3500 Classic and GMC Sierra 3500 Classic, use the dual rear wheel application noted in the fitment data.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The ABS sensor is fully tested, and the bearing and seal design is built around precision geometry, contamination control, and consistent performance characteristics.
