Timken HA590315 Wheel Bearing and Hub Assembly - Front

Timken HA590315 Front Hub Assembly

Timken HA590315 is a front wheel bearing and hub assembly built for select Subaru applications, including Forester, Impreza, Legacy, Outback, and XV Crosstrek models. It combines OE-developed testing, precision bearing construction, and integrated ABS wheel-speed sensing to support stable braking and smooth road feel.

Key Features

• Front driven hub assembly for select Subaru vehicles
• 27-spline design with 5 wheel studs and 4 flange bolt holes
• Low runout construction to reduce noise and vibration
• Precision-profile bearings with uniform internal geometry and refined surface finishes
• Premium seal design with reinforced outer case and contamination exclusion features
• ABS sensor tested to monitor wheel speed for anti-lock braking systems
• Cross-reference: SKF BR930473

Detailed Description

Timken HA590315 is engineered as a direct front hub and bearing replacement for Subaru Forester, Impreza, Legacy, Outback, and XV Crosstrek applications listed below. The assembly uses OE-developed validation methods to control design, materials, and manufacturing process, helping maintain consistent performance in daily driving and braking conditions. Its low-runout design supports quieter operation and improved brake feel, while the bearing package is built with precision profiles and enhanced surface finishes to improve load capacity and service life. Timken HA590315 also includes an ABS sensor that is 100% tested for wheel-speed monitoring. This part cross-references SKF BR930473 for the same application.

Common Issues This Part Addresses

• Front wheel bearing noise or growling
• Excessive hub play or looseness
• ABS wheel-speed signal faults tied to the hub sensor
• Brake pulsation or vibration related to hub runout
• Uneven rolling resistance from worn hub components

Installation Notes and Tips

Confirm the vehicle’s build date before ordering, since several 2014 Subaru applications are listed only through 1/13/2014. Verify spline count, bolt pattern, flange dimensions, and ABS sensor connection against the original hub before installation. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear that could affect hub performance.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed testing and controlled production methods. The bearing and seal design focus on consistent fit, contamination resistance, and long-term performance in front-wheel service applications.
