Timken HA590600K Wheel Bearing and Hub Assembly - Front

Timken HA590600K Front Hub Assembly

Timken HA590600K is a front wheel bearing and hub assembly built for driven applications that need stable wheel support, accurate wheel-speed signal performance, and consistent braking feel. It is a direct-fit option for select Nissan Maxima, Nissan Altima, INFINITI I35, and INFINITI I30 front positions.

Key Features

• Front wheel bearing and hub assembly for driven applications
• 29-spline design
• 5-wheel-stud hub with 4.5-inch bolt circle diameter
• Wheel pilot diameter: 2.588 in. / 65.74 mm
• Brake pilot diameter: 2.667 in. / 67.76 mm
• Flange diameter: 5.354 in. / 136 mm
• ABS sensor is 100% tested for wheel-speed monitoring
• Premium seals and precision bearing surfaces support smooth operation

Detailed Description

Timken HA590600K is engineered using OE-developed testing methods that guide the design, materials, and manufacturing process of the hub bearing assembly. The result is a front hub assembly with low runout characteristics that help reduce noise and vibration while supporting braking performance. Precision bearing geometry, refined internal surfaces, and premium sealing features are used to promote load capacity, bearing life, and efficient operation. This part cross-references SKF BR930600K for the same application.

Compatible With 2000-2008 Nissan Maxima, front; 2002-2006 Nissan Altima, front; 2002-2004 INFINITI I35, front; and 2000-2001 INFINITI I30, front. Timken HA590600K is a practical replacement choice when servicing a worn front hub on a Nissan Maxima or Nissan Altima with ABS-equipped driveline and axle components.

What It Helps Address

• Wheel bearing noise from a worn front hub assembly
• Vibration or runout felt through the steering or chassis
• ABS wheel-speed signal issues related to hub sensor performance
• Uneven braking feel caused by hub-related wear
• Loose or rough front wheel rotation

Installation Notes and Tips

Verify spline count, bolt circle diameter, wheel pilot diameter, and brake pilot diameter before installation. Confirm front-position fitment for the exact year and model, especially on Nissan Maxima and Nissan Altima applications. Inspect the mating surfaces, axle splines, and ABS connector routing during service to help ensure proper seating and sensor function.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The ABS sensor is 100% tested, and the sealing system is built to support contamination resistance and long-term sealing performance.
