Timken Rear Hub Assembly for Fusion, Milan, and Mazda 6

Timken HA590100 is a rear wheel bearing and hub assembly built for select Ford Fusion, Mercury Milan, and Mazda 6 applications. It combines precision bearing geometry, low runout, and ABS sensor testing to support stable wheel-speed signal performance and consistent braking feel.

Key Features

• Rear wheel bearing and hub assembly for non-driven applications
• Precision bearing profiles and uniform internal geometry for load support
• Enhanced surface finishes to help extend bearing life and improve efficiency
• 100% tested ABS sensor for wheel-speed monitoring
• Low runout design to reduce noise and vibration
• Premium seal design with reinforced outer case and contamination exclusion features
• 5 wheel studs with 4.5 in. bolt circle diameter
• Wheel pilot diameter: 67 mm; brake pilot diameter: 72 mm

Detailed Description

Timken HA590100 is engineered as a rear hub assembly for 2006-2012 Ford Fusion, 2006-2010 Mercury Milan, and 2003-2008 Mazda 6 models. The assembly uses premium bearings with controlled internal geometry and refined surface finishes to support load capacity and bearing durability. Timken also validates the ABS sensor to monitor wheel speed for anti-lock braking system operation, making this a practical replacement for rear hub service on Fusion, Milan, and Mazda 6 vehicles.

This part cross-references MOOG Hub Assemblies 512271 and SKF BR930411 for the same application. Timken HA590100 is a direct-fit style replacement for rear hub service where OE-level dimensions matter, including the 140 mm flange diameter and 5-lug, 114.3 mm bolt circle layout.

Common Problems This Part Can Address

• Rear wheel bearing noise or growling
• Excessive hub play or looseness
• ABS warning light caused by wheel-speed signal issues
• Brake vibration related to hub runout
• Uneven wheel rotation feel from worn hub components

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. Confirm the 5-lug, 114.3 mm bolt circle, 67 mm wheel pilot diameter, and 72 mm brake pilot diameter match the vehicle specification. Clean the mounting surface thoroughly and inspect the knuckle, axle area, and brake components for wear before installing the new hub assembly. For 2006-2012 Ford Fusion rear hub replacement, 2006-2010 Mercury Milan rear wheel bearing service, and 2003-2008 Mazda 6 rear hub repair, confirm ABS connector routing and sensor alignment during assembly.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process of its hub bearing assemblies. That process supports consistent performance across rear hub applications such as the Ford Fusion, Mercury Milan, and Mazda 6. Timken HA590100 is built with premium seals and tested ABS sensing components to support dependable service life.
