Common Replacement Reasons

• Rear wheel bearing noise or rough rotation
• Excessive wheel play or looseness
• Uneven rear wheel mounting or hub wear
• ABS-related service where the sensor is not transferred from the hub
• Restoring proper rear hub fitment on a Chevrolet Cobalt, Pontiac G5, or Saturn Ion

Installation Notes and Tips

Verify rear position, bolt circle diameter, and pilot dimensions before installation. Confirm that the vehicle uses a 4-lug, 100 mm bolt pattern and that the brake and hub pilot measurements match the original assembly. Because the ABS sensor is not included, transfer or service the sensor separately if required by the vehicle configuration. Always inspect related rear suspension and brake components during hub replacement.
