How to Determine if a Car Bearing is Faulty?
1 Answers
When the car is running, the wheels wobble and the overall vehicle vibration increases. Unusual noises may occur. Poor rolling can lead to a decrease in power. Here's how to check: 1. Increase speed: After increasing the speed (when the humming noise is louder), shift the gear to neutral and let the vehicle coast, observing whether the noise comes from the engine. If the humming noise remains unchanged during neutral coasting, it is likely a wheel bearing issue. 2. Temporary stop inspection: Get out and check the temperature of the wheel hubs. The method is: touch each of the four wheel hubs with your hand to roughly feel if their temperatures are consistent (under normal brake shoe and pad conditions, the front and rear wheel temperatures will differ, with the front wheels being slightly higher). If the temperature difference is not significant, you can continue driving slowly to the repair station. 3. Use a lift: Raise the car with a lift (after releasing the handbrake and shifting to neutral). If a lift is not available, use a jack to raise each wheel one by one. Manually rotate each of the four wheels quickly. When encountering a faulty axle, it will produce a distinct noise, completely different from the other axles. This method makes it easy to identify which axle has a problem.
