Timken HA590146 Wheel Bearing and Hub Assembly - Rear

Timken Rear Hub Assembly for Acura TL and RL

Timken HA590146 is a rear wheel bearing and hub assembly built for select Acura applications, including the 2009-2013 Acura TL and 2005-2012 Acura RL. It is engineered with OE-developed testing and precision bearing construction to support smooth wheel rotation, stable braking feel, and consistent wheel-speed signal performance.

Key Features

• Rear driven hub assembly for select Acura TL and Acura RL applications
• 28-spline design with 5 wheel studs and 4 flange bolt holes
• Low runout construction helps reduce noise and vibration
• Premium seals use reinforced materials and contamination control features to support seal life
• Precision bearing profiles and enhanced surface finishes help increase load capacity and bearing life
• ABS sensor is 100% tested for wheel-speed monitoring in Anti-lock Braking Systems
• Cross-reference: MOOG Hub Assemblies 512321 and SKF BR930606

Detailed Description

Timken HA590146 is a rear wheel bearing and hub assembly for driven rear applications. It is built with a 152.50 mm flange diameter, 120.00 mm bolt circle diameter, 81.60 mm hub pilot diameter, 64.00 mm wheel pilot diameter, and 70.00 mm brake pilot diameter. These dimensions matter when replacing a worn hub on a 2009-2013 Acura TL or a 2005-2012 Acura RL, where proper fit and wheel-speed accuracy are critical. Timken HA590146 combines precision bearing geometry with a tested ABS sensor to support reliable operation in everyday driving.

What It Helps Fix

• Wheel bearing noise from a worn rear hub assembly
• Vibration or roughness felt through the rear of the vehicle
• ABS warning light concerns related to wheel-speed signal issues
• Brake pulsation or inconsistent braking feel caused by hub runout
• Excessive play or looseness at the rear wheel hub

Installation Notes and Tips

Confirm rear fitment by year, model, and driven application before installation. Inspect the mating surfaces, axle splines, and brake components for wear or contamination before mounting the new hub assembly. Because this part includes an ABS sensor, verify connector routing and sensor alignment during installation, and torque all fasteners to the vehicle manufacturer’s specifications.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process for its hub bearing assemblies. The result is a rear hub assembly built around precision bearing profiles, uniform internal geometry, and tested ABS functionality for select Acura TL and Acura RL vehicles.
