Detailed Description

Timken HA590269 is a rear wheel bearing and hub assembly engineered for vehicles that demand accurate hub alignment and dependable wheel-speed feedback. It fits 2018-2023 Lexus LC500, 2018-2023 Lexus LC500h, 2018-2023 Lexus LS500, 2018-2023 Lexus LS500h, 2021-2023 Toyota Mirai, 2007-2017 Lexus LS460, and 2008-2016 Lexus LS600h, all in the rear position. The hub uses a 120.00 mm bolt circle, 158.00 mm flange diameter, 87.36 mm hub pilot diameter, and 68.80 mm flange offset to match the specified application.

Timken applies OE-developed testing to the design, materials, and manufacturing process of its hub bearing assemblies. The bearing package uses precision profiles, enhanced surface finishes, and controlled internal geometry to support smoother rotation and improved fuel efficiency. The seal design includes a reinforced outer case, ribbed inner diameter, contamination exclusion features, and vent holes to help protect the seal during installation and maintain sealing performance over time. The integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems.

What It Helps Solve

• Rear wheel bearing noise
• Hub-related vibration or runout concerns
• ABS wheel-speed signal faults tied to the hub assembly
• Uneven braking feel caused by hub instability
• Seal wear from contamination intrusion

Installation Notes and Tips

Confirm rear fitment by year, make, and model before installation. Verify spline count, bolt circle diameter, flange offset, and pilot diameters against the original part to ensure proper alignment on Lexus LS460, Lexus LS500, Lexus LC500, and Toyota Mirai applications. Inspect the mating surfaces, axle interface, and ABS connector condition during replacement, and follow the vehicle service procedure for torque and sensor routing.

Quality Assurance

Timken uses OE-developed test methods to control hub bearing design, materials, and manufacturing process. The HA590269 is built with premium bearing surfaces, reinforced sealing features, and a tested ABS sensor to support consistent performance in rear driveline and axle service.
