What This Part Helps Address

• Front wheel bearing noise or rough rotation
• Excessive wheel play or looseness at the hub
• Vibration caused by a worn hub assembly
• Improper wheel mounting due to damaged pilot surfaces
• Service replacement for a failed front hub on the listed GM models

Installation Notes and Tips

Confirm the vehicle’s year, make, model, and front position before installation. Verify spline count, bolt circle, pilot diameters, and flange dimensions against the original part to ensure correct match-up. Because the ABS sensor is not included, reuse or transfer the vehicle’s existing sensor setup if required by the application. Always inspect related suspension and brake components during hub replacement.
