Timken HA590626 Wheel Bearing and Hub Assembly - Front

Wheel Bearing and Hub Assembly Overview

Timken HA590626 is a wheel bearing and hub assembly built for front applications on select Lexus crossover models. It is engineered with OE-developed testing, precision bearing surfaces, and sealing features that support smooth operation, reduced noise, and stable wheel-speed signal performance.

Key Features

• OE-developed testing helps control design, materials, and manufacturing process.
• Low runout helps reduce noise and vibration while supporting braking performance.
• Premium seals use reinforced construction and contamination control features.
• Precision bearing profiles and uniform internal geometry support load capacity and bearing life.
• ABS sensor is fully tested to monitor wheel speed for anti-lock braking systems.

Detailed Description

This Timken hub assembly is designed for front fitment on 2015-2021 Lexus NX300h, 2015-2017 Lexus NX200t, and 2018-2021 Lexus NX300. The HA590626 combines premium bearings, enhanced surface finishes, and a sealed design to help maintain consistent wheel support and smooth rotation under everyday driving conditions. This part cross-references MOOG Hub Assemblies (e.g., 513424) and SKF (e.g., BR931146) for the same application.

Timken applies OE-developed validation to the hub bearing assembly process, with attention to materials and manufacturing consistency. The result is a front wheel bearing and hub assembly intended to maintain proper wheel-speed sensing, reduce unwanted vibration, and support long service life in Lexus NX300, NX300h, and NX200t applications.

What It Is Used For

• Wheel noise caused by worn bearing surfaces
• Vibration felt through the chassis or steering
• ABS warning concerns related to wheel-speed signal issues
• Uneven or rough hub rotation
• Reduced braking smoothness from excessive hub runout

Installation Notes and Tips

Confirm front fitment by year, model, and application details before installation. Inspect the mating surfaces, axle interface, and surrounding suspension components for wear or contamination before mounting the new hub assembly. Verify ABS sensor connection and wheel-speed system operation after installation.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process of its hub bearing assemblies. The integrated ABS sensor is 100% tested for wheel-speed monitoring performance.
