Product Description

InMotion WA512246 is manufactured as a direct replacement wheel hub assembly for the listed vehicles, including Cadillac CTS and Cadillac STS front applications as well as rear applications for Saturn Relay, Buick Terraza, Chevrolet Uplander, and Pontiac Montana. The assembly is produced with controlled tolerances and OE-based measurements to help ensure proper hub location, wheel mounting alignment, and ABS sensor integration. If you are replacing a worn hub on a 2003-2007 Cadillac CTS or a 2005-2011 Cadillac STS, this part number WA512246 is built to match the original application requirements.

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

Common Replacement Reasons

• Wheel bearing noise or rough rotation
• Excessive wheel play or looseness at the hub
• ABS warning light related to hub sensor failure
• Uneven wheel mounting caused by worn hub surfaces
• Vibration or instability from a deteriorated hub assembly

Installation Notes

Confirm the vehicle position before ordering, since WA512246 is used on front and rear applications depending on the model. Verify the wheel pilot diameter, bolt circle diameter, flange offset, and brake pilot diameter against the original part before installation. Because the ABS sensor is included, inspect the connector and wiring condition during service to avoid false fault codes after replacement.

Quality Assurance

InMotion manufactures this hub assembly using high-precision processes and strict quality-control criteria. Each unit is built to the specified OE-based dimensions for fitment, performance, and service life on the listed Cadillac, Saturn, Buick, Chevrolet, and Pontiac applications.
