Timken 512123 Wheel Bearing and Hub Assembly - Rear

Timken 512123 Rear Wheel Bearing Hub Assembly

Timken 512123 is a rear wheel bearing and hub assembly for select Acura RL and Honda Odyssey applications. It combines OE-developed testing, precision bearing construction, and integrated ABS sensing to support smooth wheel rotation, stable braking response, and consistent wheel-speed monitoring.

Key Features

• Rear wheel bearing and hub assembly for non-driven applications
• Fits 1996-2001 Acura RL, rear
• Fits 1998 Honda Odyssey, rear
• 5-wheel-stud hub with 4.5 in. bolt circle diameter
• 64 mm wheel pilot diameter and 146.5 mm flange diameter
• Low runout construction helps reduce noise and vibration
• Premium seals help resist contamination and support seal life
• Precision bearing profiles and enhanced surface finishes support load capacity and bearing life
• ABS sensor is 100% tested for wheel-speed monitoring

Detailed Description

Built for rear axle service, Timken 512123 is a direct-fit hub bearing assembly for 1996-2001 Acura RL and 1998 Honda Odyssey models. The assembly uses precision internal geometry and controlled manufacturing processes to help maintain consistent wheel rotation, reduce runout, and support braking performance. Timken 512123 also includes an ABS sensor that is tested to monitor wheel speed for anti-lock braking system operation.

Important dimensions include a 62 mm flange offset, 70 mm brake pilot diameter, 64 mm wheel pilot diameter, and 5-stud mounting with a 114.3 mm bolt circle. These specifications matter when replacing a worn rear hub on an Acura RL or Honda Odyssey, especially when addressing wheel noise, vibration, or ABS warning concerns.

This part cross-references Monroe Shocks & Struts (e.g., BR930185) for the same application.

What It Helps Fix

• Rear wheel bearing noise or growling
• Wheel vibration or runout-related drivability issues
• ABS wheel-speed signal faults tied to a failing hub sensor
• Uneven braking feel caused by hub wear
• Excessive play at the rear wheel hub

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. Inspect the knuckle, axle area, and mating surfaces for corrosion or damage, and confirm the ABS connector and sensor routing match the original setup. Because hub assemblies are precision components, clean mounting surfaces and correct torque procedures are important for proper seating and long-term performance.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process behind this hub bearing assembly. The result is a component built to maintain consistent performance, with premium seals, precision bearings, and a tested ABS sensor for dependable rear-wheel service.
