Chevrolet Cruze / Buick New Regal Rear Wheel ABS Sensor 12841558 Replacement Part

When your Chevrolet Cruze or Buick LaCrosse/Cusso (Regal) shows ABS warning on the instrument cluster, or wheels lock during emergency braking, usually the rear wheel ABS sensor has aged and failed to accurately transmit wheel speed signals. The sensor normally monitors wheel speed and transmits data to the ABS control module to ensure proper brake force modulation in emergencies, preventing wheel lock and maintaining steering. This is a replacement part, OEM number 12841558, compatible with Chevrolet Cruze and Buick LaCrosse, Regal, etc. During installation, clean mounting holes, avoid foreign objects, ensure proper gap between sensor and tone ring, and tighten to original standards to avoid signal issues or warning lights.
