• 5-lug hub pattern with 4 flange bolt holes
• Bolt circle diameter: 4.500 in. / 114.30 mm
• Wheel pilot diameter: 2.598 in. / 66.00 mm
• Brake pilot diameter: 2.677 in. / 68.00 mm
• Hub pilot diameter: 3.661 in. / 93.00 mm
• Flange diameter: 5.354 in. / 136.00 mm
• Flange offset: 1.614 in. / 41.00 mm

Detailed Description

Timken HA590376 is engineered for front axle service on a wide range of Nissan 370Z, Nissan Z, and INFINITI models, including the Q50, Q60, Q70, Q70L, QX50, QX70, G37, G35, M35, M37, M56, FX35, FX37, EX35, EX37, G25, M45, and Q40. This front wheel bearing hub assembly uses precision bearing surfaces and controlled internal geometry to support smooth rotation, reduced friction, and consistent wheel-end performance. The sealed design helps keep contaminants out, while the integrated ABS sensor supports accurate wheel speed signal monitoring for anti-lock braking systems. Timken HA590376 is a direct-fit style replacement for front wheel-end service on these applications.

This part cross-references SKF BR930890 and 533334 for the same application.

Common Problems This Part Can Address

• Front wheel bearing noise or growling from the hub area
• Steering wheel or chassis vibration related to hub runout
• ABS warning light caused by wheel speed sensor signal issues
• Uneven braking feel linked to worn front hub components
• Excessive play or rough rotation in the front wheel end

Installation Notes and Tips

Verify front position, bolt pattern, pilot diameters, and ABS connector details before installation. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear that could affect hub performance. Follow the vehicle service procedure for torque specifications and sensor handling to avoid damage during installation.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process behind this hub bearing assembly. The result is a front hub unit built to maintain consistent performance, sealing integrity, and ABS sensor function across the listed Nissan and INFINITI applications.
