Detailed Product Overview

This InMotion hub assembly is manufactured with high-precision processes and strict quality-control standards to match the designated application. The assembly uses a 100.0 mm bolt circle diameter, 135.0 mm flange diameter, 60.0 mm flange offset, 73.9 mm hub pilot diameter, 54.0 mm wheel pilot diameter, and 55.0 mm brake pilot diameter. Those measurements help support correct wheel seating, brake alignment, and hub installation on the rear of the vehicle. If you are replacing a worn rear hub on a Toyota Prius or Toyota Prius Plug-In, WA512505 provides a direct-fit service part built around OE measurements.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Rear wheel bearing noise or growling
• Excessive wheel play or looseness
• ABS warning light caused by a failed hub sensor
• Uneven rear wheel rotation from hub wear
• Vibration or roughness from a damaged rear hub assembly

Installation Notes and Tips

Confirm rear fitment by year and model before installation. Inspect the knuckle, axle area, and brake components for wear or damage before mounting the new assembly. Because the ABS sensor is included, verify connector routing and sensor seating during installation. Torque all fasteners to the vehicle manufacturer’s specifications and check wheel bearing operation after installation.

Quality Assurance

InMotion manufactures this hub assembly using OE data and measurements, with controlled production standards intended to support proper fitment and long-term service. WA512505 is built as a direct replacement for the original rear hub assembly on the listed Toyota Prius and Prius Plug-In applications.
