What Causes Abnormal Noise from the Rear Wheel of a Car?
2 Answers
The abnormal noise from the right rear wheel of a car may be caused by insufficient lubrication of the wheel hub bearing, unstable tire pressure, or aging of the shock absorber rubber sleeve. If the chassis makes unusual noises while the car is moving, it is necessary to go to a 4S shop for inspection and correction. Below is an introduction to abnormal brake noise: 1. Abnormal brake noise in a new car is normal, and the noise usually disappears after running-in for more than 200 kilometers, so there is no need to worry. 2. Replacing new friction pads or new brake discs may cause abnormal noise because the new brake discs cannot immediately achieve good run-in with the friction pads. 3. After wading through water or driving on muddy roads during off-roading, hard sand and gravel may enter the gaps in the braking mechanism, causing jamming during braking system operation and resulting in abnormal noise when they reach the gaps in the brake discs. 4. Poor fixation of the brake caliper or brake disc is another cause of abnormal brake noise and can also lead to uneven brake wear. 5. Excessive wear of the brake disc or breakage of the brake pads, even if not heavily worn, can also cause abnormal brake noise.
I've been driving for over a decade, and rear wheel noise is a common issue. The most frequent cause is bearing problems – when the car makes a humming sound that gets louder with speed, especially noticeable during turns, it's usually a sign of a worn wheel hub bearing that needs replacement. The braking system is another major culprit. For instance, worn brake pads can cause a high-pitched squeal when the metal contacts the rotor, or loose calipers might produce a clunking noise on bumpy roads. Suspension issues, like aging bushings, can lead to creaking sounds, and it's not uncommon to hear a tapping noise from small stones stuck in the tire treads. When dealing with such noises, first park safely and try to identify the source and type of sound. If the noise is persistent and severe, don't hesitate – take the car straight to a repair shop for inspection. Safety first to prevent accidents. From my experience, regular maintenance and timely replacement of parts save both hassle and money in the long run.
