• Premium seal design with contamination control features
• ABS sensor function is 100% tested for wheel-speed monitoring

Detailed Description

Timken HA590496 is a direct-fit rear hub assembly for Mazda 6 and Mazda CX-5 models listed in the fitment data. The assembly is built with low runout to reduce noise and vibration, while the premium bearing design helps maintain consistent wheel support under everyday driving loads. Timken also uses reinforced sealing features and tested ABS sensor performance to support reliable operation in vehicles equipped with anti-lock braking systems. This part cross-references MOOG Hub Assemblies 512519 and SKF BR930967 for the same application.

Common Problems This Part Can Address

• Rear wheel noise from a worn hub bearing
• Vibration felt through the chassis or steering during driving
• Brake pulsation or inconsistent braking feel related to hub runout
• ABS warning light caused by a failing wheel-speed sensor circuit
• Excessive play or looseness at the rear wheel hub

Installation Notes and Tips

Confirm rear-position fitment before ordering, since this assembly is not for driven axle locations. Verify the bolt pattern, pilot diameters, and flange dimensions against the original part before installation. Clean the mounting surface thoroughly and inspect surrounding brake and suspension components for wear that could affect hub performance.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures that control design, materials, and production processes. The result is a rear hub assembly built to meet the dimensional and performance requirements expected for Mazda 6 and Mazda CX-5 rear applications.
