What is a wheel hub?

A wheel hub is a component of a vehicle's wheel assembly that connects the wheel to the axle. It is typically located at the center of the wheel and contains bearings that allow the wheel to rotate smoothly. The hub also provides a mounting point for the wheel studs or bolts that secure the wheel to the vehicle.

Wheel hubs are made from a variety of materials such as steel, aluminum, or an alloy combination, depending on the specific application and performance requirements. Some wheel hubs are designed to be integrated with the wheel bearing assembly, while others may require separate bearing installation.

Maintaining the wheel hubs is important for the overall performance and safety of the vehicle. Regular inspection and maintenance of the wheel hubs can help prevent issues such as wheel wobble, uneven tire wear, and wheel misalignment. If a wheel hub becomes damaged or worn out, it should be replaced by a qualified mechanic to ensure the vehicle's safety and performance.
