The signs of damage to the front wheel bearings of a sedan are: 1. A loud humming noise is heard after the car is driven; 2. The temperature rises because the damaged front wheel bearings increase friction, generating a lot of heat, and the area will feel hot to the touch; 3. When the car is lifted with a jack and the tire is shaken, there will be play. The main function of the bearings is to bear the load and provide precise guidance for the rotation of the hub. They bear both axial and radial loads, making them a very important component. The wheel bearings in traditional cars are composed of two sets of tapered roller bearings or ball bearings combined. The installation, greasing, sealing, and adjustment of the bearing clearance are all carried out on the automobile production line.
If you encounter a front wheel bearing failure while driving, I can tell you from experience that the main symptom is a humming noise. As the speed increases, say from 30 mph to 60 mph, you'll hear a continuous low rumbling sound, like the tires are grinding against something, especially noticeable when turning. The steering wheel may also shake or wobble at high speeds, with reduced grip, causing unstable turns or slight vehicle drift. Long-term neglect can accelerate tire wear, loosen the wheel, or even risk detachment. Once, while driving a friend's car, I noticed the sound getting louder and the wheel becoming unbalanced. Fortunately, I sent it for repair in time to replace the bearing and avoided an accident. I recommend getting it checked as soon as you hear unusual noises, don't wait for it to worsen.
