Built Around Timken Bearing Standards

Timken HA590119 is manufactured using OE-developed testing methods that guide the design, materials, and production process of the hub bearing assembly. The bearing uses precision profiles, uniform internal geometry, and enhanced surface finishes to support load capacity and bearing life, while low runout helps reduce noise and vibration. Premium seal construction adds contamination exclusion features and venting details to improve sealing performance during installation and service.

This part cross-references SKF BR930474 for the same application.

Vehicle Fitment

• Fits 2005-2009 Subaru Legacy, rear.
• Fits 2005-2009 Subaru Outback, rear.

Common Repair Uses

• Rear wheel bearing noise or growling
• Wheel vibration at speed
• ABS wheel speed signal faults
• Excessive hub play or looseness
• Uneven braking feel related to hub runout

Installation Notes and Tips

Confirm rear fitment by matching the vehicle year, model, and driven hub configuration before installation. Inspect the knuckle, axle splines, and mounting surfaces for wear or corrosion, and verify the ABS connector and tone signal path are clean and undamaged. Proper torque and clean mating surfaces are important to maintain hub alignment and reduce runout.

Quality Assurance

Timken uses OE-developed test procedures to control hub assembly design, materials, and manufacturing consistency. The HA590119 is engineered with tested ABS sensing, precision bearing surfaces, and seal features intended to support reliable service on Subaru Legacy and Subaru Outback rear applications.
