Timken HA590325 Wheel Bearing and Hub Assembly - Rear

Timken Rear Wheel Hub Assembly

Timken HA590325 is a rear wheel bearing and hub assembly built for select Hyundai Sonata and Kia Optima applications. It combines precision bearing geometry, low runout, and integrated ABS sensing to support stable wheel-speed monitoring, quieter operation, and consistent braking feel.

Key Features

• Rear wheel bearing and hub assembly for non-driven applications
• 5 wheel studs with a 4-bolt flange pattern
• 4.500 in. bolt circle diameter for confirmed OE-style fitment
• Integrated ABS sensor with 100% tested wheel-speed monitoring
• Premium seals with reinforced construction to help keep contamination out
• Precision bearing profiles and enhanced surface finishes for load support and bearing life
• Low runout design to reduce noise and vibration

Detailed Description

Timken HA590325 is engineered for rear axle service on 2006-2010 Hyundai Sonata and 2006-2010 Kia Optima applications listed below. The hub assembly uses OE-developed testing methods to control design, materials, and manufacturing processes, helping maintain consistent performance in daily driving conditions. Timken HA590325 also features an integrated ABS sensor, making it a direct choice for vehicles that rely on wheel-speed input for anti-lock braking and stability-related functions.

This part cross-references Monroe Shocks & Struts (e.g., 172286) and SKF (e.g., BR930733) for the same application.

What It Helps Solve

• Wheel bearing noise from worn rear hub components
• Brake pulsation or vibration related to hub runout
• ABS warning lights caused by wheel-speed sensor issues
• Loose or inconsistent wheel support at the rear axle
• Contamination-related bearing wear from failed seals

Installation Notes and Tips

Verify rear fitment by year, make, model, and application notes before installation. Fits 2009-2010 Hyundai Sonata, rear; Fits 2006-2008 Hyundai Sonata, rear, Electronic Stability; Fits 2009-2010 Kia Optima, rear; Fits 2006-2008 Kia Optima, rear, New Style. Confirm the bolt circle, flange dimensions, and ABS connector routing match the original hub before assembly. Clean the mounting surface and inspect adjacent brake and suspension components during service.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed testing and controlled production methods. The bearing design, seal construction, and ABS sensor testing are focused on consistent fit, wheel-speed accuracy, and long service life in the specified Hyundai Sonata and Kia Optima rear applications.
