What It Helps Fix

• Wheel bearing noise or rough rotation
• Excessive wheel play or looseness at the hub
• ABS-related service needs when the sensor is not part of the assembly
• Improper wheel mounting caused by worn hub surfaces
• Vibration or instability related to hub wear

Installation Notes

Verify the vehicle position before ordering, since MOOG 512661 is listed for rear applications on the Chevrolet Malibu, Buick LaCrosse, Buick Envision, and Buick Regal Sportback, and for the front on the Cadillac CT4. Confirm flange bolt hole quantity, bolt circle diameter, pilot diameters, and wheel stud count against the original part before installation. Because the anti-lock brake sensor is not included, transfer or service the sensor separately if the vehicle requires one.
