What are the consequences of abnormal noise from car wheel bearings?

[SanMary]

"Abnormal noise from car wheel bearings indicates wear, looseness, or lack of lubrication in the bearings, which can cause the bearings to seize, affecting the comfort of the car. It can also increase driving resistance, and in severe cases, damage the wheel mechanism, leading to hub detachment and compromising driving safety. When the car's bearings are damaged, the car will emit a continuous humming sound. If you accelerate the car to a certain speed and then coast in neutral, and the humming sound remains unchanged, it can be concluded that the noise is caused by damaged wheel bearings. Another symptom is that when the car is stationary or moving at low speeds, turning the steering wheel may produce a squeaking sound. In severe cases, you may even feel vibrations in the steering wheel. It is easy to distinguish between tire noise and abnormal sounds caused by bearing damage. The noise from damaged bearings is a continuous humming sound, like metal rubbing, whereas tire noise does not produce this sound. Additionally, when driving on rough roads, tire noise becomes more pronounced, whereas abnormal sounds caused by bearing damage do not change with road roughness."
