Detailed Description

InMotion WA512287 is a rear wheel bearing and hub assembly for 2004-2007 Chevrolet Malibu, 2006-2007 Chevrolet HHR, and 2005-2007 Pontiac G6. It is built as a direct replacement for the original rear hub assembly and uses OE measurements to match the intended application. The precision-machined hub design supports proper wheel mounting and dependable rotation at the rear axle.

This part number, WA512287, is a practical choice when replacing a worn rear hub on a Chevrolet Malibu, Chevrolet HHR, or Pontiac G6. The assembly is specified without an ABS sensor, so the existing vehicle configuration should be verified before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Rear wheel bearing noise or growling
• Excessive wheel play or looseness at the hub
• Uneven rear wheel rotation caused by hub wear
• Vibration or roughness from a worn rear bearing assembly
• Replacement needs after hub or bearing service on the rear axle

Installation Notes and Tips

• Confirm rear-position fitment before ordering: Fits 2004-2007 Chevrolet Malibu, rear; Fits 2006-2007 Chevrolet HHR, rear; Fits 2005-2007 Pontiac G6, rear.
• Verify the vehicle does not require an ABS sensor in the hub assembly, since this unit is listed without one.
• Check bolt circle, pilot diameters, and flange offset against the original part before installation.
• Inspect related rear suspension and brake components for wear while the hub is removed.
