Detailed Fitment and Design

The InMotion WA512209HD is built for rear-wheel applications on the 2004-2006 Scion xA, 2004-2006 Scion xB, and 2000-2005 Toyota Echo. It is manufactured with high-precision processes and strict quality-control standards, then matched to OE measurements so the hub assembly aligns correctly with the wheel, brake, and sensor interfaces. The included ABS sensor supports vehicles that rely on integrated wheel speed sensing at the hub.

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 such as humming, growling, or rumbling
• Excessive wheel play or looseness at the hub
• ABS warning light caused by a failed hub-mounted sensor
• Uneven wheel rotation from worn hub components
• Vibration or instability from a deteriorated rear hub assembly

Installation Notes and Tips

Confirm rear position and verify bolt circle, pilot diameters, and stud count before installation. Clean the mounting surface thoroughly, inspect the knuckle and brake components for wear, and follow the vehicle service manual for torque specifications and ABS system procedures. For 2004-2006 Scion xA, 2004-2006 Scion xB, and 2000-2005 Toyota Echo rear service, matching the sensor connection and hub dimensions is important for proper operation.
