OE-Style Fit and Construction

The hub assembly is designed as a direct replacement for the original rear unit on Corolla and Prizm models, using OE measurements to align the wheel mounting surface, pilot diameters, and bolt pattern. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Addresses

• Rear wheel bearing noise or growling
• Excessive wheel play or looseness at the hub
• Uneven wheel mounting caused by worn hub components
• Vibration from a damaged rear hub assembly
• Corrosion or wear at the wheel bearing mounting surface

Installation Notes

Confirm rear fitment by year, make, and model before ordering. Match the 4-lug bolt pattern, 100.0 mm bolt circle diameter, and pilot dimensions to the original part. Because the ABS sensor is not included, reuse or source the vehicle’s existing sensor setup as required by the application. Professional installation is recommended for proper torque, bearing seating, and final inspection.
