A-Premium Front Wheel Hub Bearing Assembly for Chevy Buick – Front Left/Right, Integrated ABS, Sealed Bearing

The A-Premium Front Wheel Bearing Hub Assembly is a direct-fit replacement hub with integrated ABS sensor designed to restore smooth wheel rotation and eliminate noise, vibration, and grease leakage on compatible GM vehicles.

If your Chevrolet, Buick, Cadillac or compatible GM vehicle shows humming, grinding, or dashboard ABS warnings, a worn wheel hub bearing assembly is often the source. This A-Premium unit replaces the entire front hub assembly (left or right) and includes a sealed bearing, molded ABS cable grommet and corrosion-resistant sealing to simplify installation and improve reliability.

How will this hub assembly improve steering stability and noise?

Replacing a degraded hub assembly removes play between the wheel and spindle, reducing vibration and wheel wander under load. The integrated sealed bearing and precision raceways ensure even rolling and quieter operation after installation.

• Sealed inboard/outboard design resists dirt and water intrusion
• Factory-alike bearing raceways for consistent wheel support
• 33-spline hub for accurate drivetrain engagement
• Built-in ABS sensor to restore proper wheel-speed readings
