What Are the Effects of a Bad Car Bearing?

[GiselleLee]

Minor effects include reduced comfort: increased tire noise and vehicle deviation; while severe consequences can lead to suspension damage: causing steering system failure and resulting in traffic accidents. Below are specific methods to determine if a car bearing is damaged: 1. Open the car window to listen if the noise is coming from outside the vehicle. 2. Increase the speed and then shift to neutral to let the vehicle coast, observing whether the noise originates from the engine. If the humming noise remains unchanged while coasting in neutral, it is likely a wheel bearing issue. 3. Make a temporary stop, get out of the car, and check if the axle temperature is normal. Touch each of the four wheel hubs by hand to roughly feel if their temperatures are consistent. If the difference is minimal, continue driving slowly to the repair station. 4. Lift the car with a lift; if a lift is unavailable, use a jack to raise each wheel one by one. Manually rotate each of the four wheels quickly. When encountering a problematic axle, it will produce a noise distinctly different from the others. This method easily identifies which axle has an issue.
