Fitment Details

Compatible with rear applications on 2002-2007 Saturn Vue, rear; 2006 Pontiac Torrent, rear; and 2005 Chevrolet Equinox, rear. This fitment coverage makes WA512230 a direct replacement option for common rear hub service on these platforms.

WA512230 is built with high-precision manufacturing and strict quality-control criteria to match the original part’s dimensions and mounting points. The assembly is designed for vehicles that require a rear hub with a 33-spline interface, 5-stud wheel mounting, and the specified pilot and bolt-circle measurements. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Wheel bearing noise from the rear hub area
• Excessive wheel play or looseness
• Uneven wheel rotation or rough hub operation
• Hub mounting wear on Saturn Vue, Chevrolet Equinox, or Pontiac Torrent rear axles
• Replacement after bearing or hub seal deterioration

Installation Notes

Confirm rear position, spline count, bolt circle, and pilot diameters before installation. Because the ABS sensor is not included, reuse or transfer the vehicle’s existing sensor setup if required by the application. Always inspect the mating surfaces, axle condition, and fasteners during hub replacement.

Quality Assurance

InMotion manufactures this hub assembly using OE data and dimensional measurements to support proper fitment and consistent performance. The part is produced under strict quality-control criteria for direct-replacement service on the listed vehicles.
