1. Grinding or humming noise: A constant grinding or humming noise that changes in pitch with speed may indicate worn wheel bearings.
2. Increased noise when turning: The noise may become louder or more noticeable when you turn the steering wheel to one side or the other.
3. Play or movement in the wheel: If there is excessive play or movement in the wheel when you try to wiggle it by hand, the wheel bearings may be worn.
4. Uneven tire wear: Premature or uneven wear on the inside or outside edge of the tire tread may also be a sign of worn wheel bearings.
If you hear any of these noises or notice these symptoms, it's a good idea to get your vehicle inspected by a qualified mechanic to identify the source of the noise and determine if the wheel bearings need to be replaced.
