Timken HA590128 Wheel Bearing and Hub Assembly - Rear

Rear Hub Bearing Assembly for Mitsubishi

Timken HA590128 is a rear wheel bearing and hub assembly built for select Mitsubishi applications, including the 2006-2012 Mitsubishi Eclipse and 2004-2012 Mitsubishi Galant. It combines precision bearing construction with OE-developed testing standards to support stable wheel support, smooth rotation, and consistent braking feel.

• Rear wheel bearing and hub assembly for non-driven applications
• 5 wheel studs with a 4-bolt flange pattern
• Bolt circle diameter: 4.500 in. / 114.30 mm
• Wheel pilot diameter: 2.669 in. / 67.80 mm
• Brake pilot diameter: 2.717 in. / 69.00 mm
• Hub pilot diameter: 2.560 in. / 65.00 mm
• Flange diameter: 5.433 in. / 138.00 mm
• Flange offset: 2.323 in. / 59.00 mm

Built for Smooth Rotation

Timken HA590128 uses precision-profile bearings with uniform internal geometry and refined surface finishes to support load capacity, bearing life, and fuel efficiency. Low runout helps reduce noise and vibration, while the sealed design helps maintain cleaner operation. This part cross-references MOOG Hub Assemblies (e.g., 512274) and SKF (e.g., BR930499) for the same application.

Vehicle Fitment

• Fits 2006-2012 Mitsubishi Eclipse, rear.
• Fits 2004-2012 Mitsubishi Galant, rear.

Common Replacement Reasons

• Wheel bearing noise from the rear of the vehicle
• Vibration or roughness at speed
• Excessive wheel play or looseness
• ABS wheel speed signal concerns
• Uneven braking feel related to hub wear

Installation Notes

Confirm rear position, bolt pattern, pilot diameters, and ABS sensor configuration before installation. Clean the mounting surface thoroughly and inspect related hardware, knuckles, and brake components for wear or damage. Proper torque and alignment procedures help preserve hub life and braking performance.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test methods that control design, materials, and production processes. The ABS sensor is 100% tested to monitor wheel speed for anti-lock braking systems, and the premium seal design helps resist contamination and support long service life.
