A front wheel bearing assembly is part of the wheel unit that makes the car move smoothly. The assembly is situated in the center of the wheels.
The assembly is designed to hold other parts together, including the wheel bearings. It also secures the wheel to the body of the vehicle. The bearings inside of the assembly ensure that when the wheel turns, it does so quietly. If there is an issue with the assembly, drivers will most often hear a squealing or grinding noise. When this occurs, they should get the vehicle checked by a mechanic to ensure it is safe to drive.
