Detailed Description

Timken HA590147 is a front wheel bearing and hub assembly engineered for the Acura RL platform from 2005 through 2012. It uses precision-machined bearing surfaces, enhanced internal geometry, and controlled sealing features to help maintain smooth wheel operation and consistent braking feel. The hub assembly is built for driven front applications and includes the dimensional details needed for proper alignment with the wheel, brake, and hub interfaces.

Important dimensions include a 64.00 mm wheel pilot diameter, 70.00 mm brake pilot diameter, 91.10 mm hub pilot diameter, 47.50 mm flange offset, and 152.50 mm flange diameter. These specifications matter when replacing a worn front hub on an Acura RL, especially when addressing wheel play, bearing noise, or ABS-related concerns. Timken HA590147 is also cross-referenced to MOOG Hub Assemblies 513252 and SKF BR930755 for the same application.

Common Issues This Part Can Address

• Front wheel bearing noise or growling
• Excessive wheel play or looseness at the hub
• ABS warning light caused by a faulty wheel speed sensor signal
• Brake pulsation or uneven braking feel related to hub runout
• Vibration from worn or damaged front hub components

Installation Notes and Tips

Verify spline count, bolt pattern, pilot diameters, and flange offset before installation on your Acura RL. Clean the mounting surfaces thoroughly and inspect the axle, knuckle, and brake components for wear or damage that could affect hub alignment. Because this is a driven front hub assembly, confirm the axle engagement and ABS sensor connection during installation.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed testing and controlled design, material, and process standards. The assembly features premium seals, precision bearing surfaces, and a tested ABS sensor to support reliable operation in front-wheel service on the Acura RL.
