Detailed Description

This InMotion wheel bearing and hub assembly is manufactured with precision processes and strict quality-control standards to match the designated rear applications. The assembly is built as an OE-style replacement for Acura TL and Acura RL rear service, with dimensions and mounting geometry derived from original equipment data to help maintain correct wheel location, brake interface, and sensor integration. InMotion WA512321 is a practical choice when replacing a worn rear hub on 2009-2013 Acura TL or 2005-2012 Acura RL vehicles.

Key dimensional details include a 64.0 wheel pilot diameter, 70.0 brake pilot diameter, 81.6 hub pilot diameter, 120.0 bolt circle diameter, 152.5 flange diameter, and 60.9 flange offset. The assembly also includes a modified flange shape, 4 flange bolt holes, and an ABS sensor. These specifications matter for rear hub alignment, wheel mounting, and brake system fitment on the Acura TL and Acura RL.

What It Helps Fix

• Rear wheel bearing noise or roughness
• Excessive wheel play or looseness at the hub
• ABS warning light concerns related to the rear wheel speed sensor
• Improper wheel mounting caused by worn hub surfaces
• Vibration or driveline feel related to a deteriorated rear hub assembly

Installation Notes and Tips

Confirm rear fitment by year, model, and application notes before installation. Inspect the mating surfaces, axle area, brake components, and ABS wiring for wear or damage before installing the new hub assembly. Torque fasteners to the vehicle manufacturer’s specifications and verify proper sensor operation after installation. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.
