What sound does a bad wheel hub bearing make?

[VanMicah]

When a car's bearing is damaged, the car will emit a continuous humming sound. Here is relevant information: Introduction: A bearing is a mechanical element that restricts relative motion to the desired range of movement and reduces friction between moving parts. The design of bearings can provide free linear movement of moving parts or free rotation around a fixed axis, and can also prevent movement by controlling the vector of normal forces acting on the moving parts. Plain bearing: The simplest bearing is the plain bearing, which consists of a shaft rotating in a hole. Lubrication is used to reduce friction. In ball bearings and roller bearings, rolling elements with circular cross-sections, such as rollers or balls, are placed between the races or journals of the bearing assembly to reduce sliding friction.
