How to Determine if a Car Wheel Bearing is Damaged?
1 Answers
Methods to determine if a car wheel bearing is damaged are as follows: 1. Open the car window and listen to see if the abnormal noise is coming from outside the vehicle. 2. After increasing the speed (when the humming sound is louder), shift the gear to neutral and let the vehicle coast, observing whether the noise comes from the engine. If the humming sound remains unchanged during neutral coasting, it is likely that the wheel bearing has an issue. 3. Temporarily stop the car, get out, and check if the temperature of the wheel axle is normal. The method is: touch each of the four wheel hubs with your hand to roughly feel if the temperature is consistent (when the brake shoe and pad gaps are normal, there is a temperature difference between the front and rear wheels, with the front wheels being slightly higher). If the difference is not significant, you can continue driving slowly to the repair station. 4. Use a lift to raise the car (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 problematic axle, it will make a noise that is completely different from the others. This method makes it easy to identify which axle has an issue.
