What are the symptoms of a bad wheel hub bearing?
1 Answers
The symptoms of a bad wheel hub bearing are as follows: 1. The wheels wobble when the car is moving, and the overall vehicle vibration increases. 2. Unusual noises will occur. 3. Poor rolling, leading to a decrease in power. Methods to determine if a wheel bearing is bad: 1. Open the car window to listen if the sound is coming from outside the vehicle. 2. Increase the speed (when the humming sound is louder) and shift to neutral to let the vehicle coast, observing if the noise comes from the engine. If the humming sound remains unchanged during neutral coasting, it is likely a wheel bearing issue. 3. Temporarily stop the car and check the temperature of the wheel hubs. The method is: touch each of the four wheel hubs by hand to roughly feel if their temperatures are consistent. If the difference is not significant, continue driving slowly to the repair station. 4. Lift the car with a lift (after releasing the handbrake and shifting to neutral). If a lift is not available, use a jack to lift each wheel one by one. Manually rotate each of the four wheels quickly. When encountering a problematic axle, it will make a sound that is completely different from the others. This method easily identifies which axle has an issue.
