Rear Wheel Bearing and Hub Assembly for Acura RL

InMotion WA512343 is a rear wheel bearing and hub assembly built for 2002-2004 Acura RL applications. It is engineered from OE data and measurements for direct replacement fitment, with the hub, bearing, and ABS sensor integration matched to the original design.

Key Features

• Fits 2002-2004 Acura RL, rear
• Part number WA512343 for easy identification
• 5 wheel studs with a 114.3 bolt circle diameter
• ABS sensor included for vehicles equipped with rear wheel speed sensing
• Wheel pilot diameter: 58.0 mm

• Hub pilot diameter: 87.0 mm
• Flange diameter: 146.5 mm

Detailed Description

This InMotion wheel bearing and hub assembly is manufactured with precise tolerances and quality-control standards to match the original rear hub on the Acura RL. WA512343 is designed for the rear position on 2002, 2003, and 2004 Acura RL models, making it a direct replacement option for service work that requires correct hub dimensions, stud count, and ABS sensor integration. The 5-stud, 114.3 mm bolt circle layout supports proper wheel mounting, while the listed pilot diameters help confirm fitment during parts selection. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Wheel bearing noise from a worn rear hub assembly
• Excessive wheel play or looseness at the rear axle
• ABS warning light caused by a failed hub-mounted sensor
• Uneven wheel mounting caused by damaged studs or hub surfaces
• Vibration or roughness traced to rear hub wear

Installation Notes and Tips

Confirm rear-position fitment before ordering and verify the wheel pilot, brake pilot, hub pilot, bolt circle, and stud count against the original part. Because this assembly includes an ABS sensor, inspect the connector and wiring condition during installation. Always torque wheel fasteners to the vehicle manufacturer’s specification and check for proper sensor operation after installation.

Quality Assurance

InMotion manufactures this hub assembly using OE data, measured application-specific dimensions, and strict quality-control criteria to support correct fitment and consistent performance on the 2002-2004 Acura RL rear hub application. Part number WA512343 is built as a direct replacement for the original assembly.
