Hub Bearing

Shop New OEM hub bearing assemblies for GM vehicles. Our factory-original ACDelco wheel hub and bearing units are sourced from GM surplus — the correct ABS reluctor ring configuration, bearing preload, and bolt pattern for your specific suspension.

Hub bearing failure causes wheel noise, handling instability, and ABS malfunction. OEM hub bearing units are pressed and preloaded to factory specifications — providing the correct bearing stiffness and ABS sensor air gap that your vehicle's suspension and traction control systems depend on.

Hub bearings should be replaced in axle pairs when significant wear is evident on one side. Always torque hub bolts to the factory specification. Verify part numbers against your vehicle's brake and suspension option codes.
