• 27-spline design with 5 wheel studs and 3 flange bolt holes
• ABS sensor is 100% tested for wheel speed monitoring
• Low runout construction helps reduce noise and vibration
• Premium seals are built to improve contamination resistance and sealing life
• Precision bearing profiles and enhanced surface finishes support load capacity and bearing life
• Part number 513061 is a direct reference for Timken hub assembly identification

Detailed Description

Timken 513061 is a front wheel bearing and hub assembly engineered for select 1991-1996 Chevrolet Blazer, S10, S10 Blazer, GMC Jimmy, Sonoma, S15 Jimmy, and Oldsmobile Bravada models. It features a 120.65 mm bolt circle, 144.50 mm flange diameter, 81.50 mm hub pilot diameter, and 70.10 mm wheel pilot diameter for applications that require accurate hub location and secure wheel mounting. The driven hub design and integrated ABS sensor make it a practical replacement for vehicles that rely on wheel-speed input for anti-lock braking operation. Timken uses OE-developed testing to control design, materials, and manufacturing processes, and the bearing package is built with uniform internal geometry to support smoother operation and improved efficiency. If you are replacing a worn front hub on a Chevrolet S10 or GMC Sonoma, Timken 513061 provides a specification-driven solution. This part cross-references SKF BR930064 for the same application.

What It Helps Address

• Front-end humming, growling, or bearing noise
• Wheel vibration caused by excessive hub runout
• ABS warning light concerns related to wheel speed signal loss
• Loose or inconsistent wheel mounting at the hub
• Uneven braking feel linked to worn hub bearing components

Installation Notes and Tips

Confirm front axle fitment, spline count, bolt circle, and pilot diameters before installation. Inspect the knuckle, axle interface, and mating surfaces for wear or corrosion so the new hub seats correctly. After installation, verify ABS operation and check for proper wheel torque using the vehicle manufacturer’s service procedure.

Quality Assurance

Timken manufactures this hub assembly using OE-developed test methods to control design, materials, and process consistency. Premium seals, precision bearing surfaces, and 100% tested ABS sensing support dependable performance in daily driving conditions.
