Product Description

InMotion WA512328 is a rear wheel bearing and hub assembly built for precise OE-style replacement on Subaru Tribeca and Subaru B9 Tribeca models. The assembly is manufactured with strict quality-control criteria and uses application-specific engineering to match the original fit, performance requirements, and service dimensions of the factory part. Key specifications include a 27-spline hub, 5 wheel studs, 4 flange bolt holes, and a 114.3 mm bolt circle diameter, making it a direct-fit solution for the listed rear positions.

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

Common Replacement Reasons

• Rear wheel bearing noise or growling
• Excessive wheel play or looseness
• Uneven hub wear at the rear axle
• Vibration or roughness from the wheel end
• Service replacement after hub or bearing damage

Installation Notes

Verify rear fitment by year, model, and position before installation. Confirm the hub pilot, wheel pilot, brake pilot, spline count, and bolt pattern match the original component on your Subaru Tribeca or Subaru B9 Tribeca. Because the ABS sensor is not included, reuse or source the sensor separately if your vehicle requires one.

Quality Assurance

Each InMotion WA512328 hub assembly is produced with high-precision manufacturing methods and inspected under strict quality-control standards. The part is engineered to follow OE data and measurements for consistent fitment, performance, and service life in the specified rear applications.
