Detailed Description

The Timken HA590502 front wheel bearing and hub assembly is built for vehicles that require a driven front hub with a 28-spline configuration. Key dimensions include a 63.96 mm wheel pilot diameter, 139.34 mm flange diameter, and 114.3 mm bolt circle diameter. Timken uses controlled OE-style validation to help maintain consistent fit, bearing performance, and braking feel across service replacement applications. For Acura CL, Acura TL, and Honda Accord front-end repairs, this assembly addresses worn hub bearings, wheel play, and ABS-related wheel speed concerns while maintaining the original mounting geometry.

This part cross-references SKF BR930590K for the same application.

What It Is Used For

• Front wheel bearing noise or growl from a worn hub assembly
• Excessive wheel play or looseness at the front hub
• ABS warning light caused by a faulty wheel-speed sensor signal
• Brake pulsation or vibration related to hub runout
• Uneven front-end bearing wear on Acura CL, Acura TL, or Honda Accord models

Installation Notes and Tips

Verify front-position fitment by year, make, and model before installation. Confirm the 28-spline driven hub configuration, 4.5 in. bolt circle, and pilot dimensions match the original part. Clean the mounting surface thoroughly, inspect the knuckle and axle interface for wear, and torque fasteners to the vehicle manufacturer’s specification. If the ABS system is equipped, inspect the sensor connector and wiring during replacement.

Quality Assurance

Timken manufactures this hub assembly using OE-developed test procedures, precision bearing profiles, and enhanced sealing features to support consistent performance and bearing life. The integrated ABS sensor is 100% tested for wheel-speed monitoring.
