wheel bearings
Hub rotation hardware
Wheel bearings are the components that allow a vehicle's wheels to spin freely on their axles while supporting the vehicle's weight.
They reduce friction between the rotating wheel hub and the stationary axle.
When wheel bearings wear out, they typically produce a humming or grinding noise that increases with speed: The mechanic said my wheel bearings need replacing.
