Timken HA590323 Wheel Bearing and Hub Assembly - Front

Timken HA590323 Front Hub Assembly

Timken HA590323 is a front wheel bearing and hub assembly built for driven applications that need stable wheel support, accurate ABS signal monitoring, and consistent braking feel. It fits 2008-2011 Volvo C30, front and 2006-2011 Volvo C70, front.

• 36-spline driven hub assembly for front axle applications
• 5 wheel studs with a 107 mm bolt circle diameter
• 63.15 mm wheel pilot diameter and 63.48 mm brake pilot diameter
• 131.34 mm flange diameter for proper hub-to-knuckle fitment
• Integrated ABS sensor tested to monitor wheel speed for ABS operation
• Low runout construction helps reduce noise and vibration
• Premium seals help resist contamination and support seal life
• Precision bearing geometry supports load capacity and bearing life

OE-Style Engineering

Timken uses OE-developed testing to control the design, materials, and manufacturing process behind this hub bearing assembly. The result is a front hub assembly with precision internal geometry, refined surface finishes, and sealing features that support smooth rotation and dependable wheel-speed sensing. For Volvo C30 and Volvo C70 front-end service, Timken HA590323 provides the dimensional and functional details needed for a direct replacement.

This part cross-references MOOG Hub Assemblies 513255 and SKF BR930675 for the same application.

What It Helps Fix

• Wheel bearing noise from a worn front hub assembly
• Steering vibration caused by excessive hub runout
• ABS warning lights related to wheel-speed sensor issues
• Brake pulsation or inconsistent braking feel tied to hub wear
• Loose or rough wheel rotation from bearing degradation

Installation Notes

Confirm spline count, bolt circle diameter, wheel pilot diameter, and brake pilot diameter before installation. This front hub assembly is for driven front applications, so verify vehicle configuration and match the original hub dimensions on the Volvo C30 or Volvo C70 before service. Clean the mounting surfaces and inspect related suspension and brake components during replacement.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test controls and 100% tested ABS sensors to support consistent performance and wheel-speed monitoring. The brand’s sealing and bearing design details are focused on durability, contamination resistance, and stable operation in daily driving.
