Rear wheel abnormal noise is dangerous, and you should promptly go to a repair shop for inspection and maintenance of the vehicle. The following introduces the causes of abnormal noise in the rear wheels of a car: 1. Suspension-related issues: The car's suspension includes links, springs, shock absorbers, and stabilizer bars. If any of these components are abnormal, such as loose bolts, it may cause abnormal noise due to shaking. 2. Problems with the braking system: For example, excessively thin brake pads, uneven wear between the brake disc and brake pads, or faults in the brake caliper, master cylinder, or wheel cylinder can all lead to abnormal noise in the braking system, mainly manifested as sharp and continuous sounds.

Hearing strange noises from the rear wheels makes me nervous. This is no minor issue – severe bearing wear can cause wheel lock-up or detachment, leading to loss of control and skidding at high speeds, potentially resulting in accidents. If it's a brake component issue, like loose calipers or increased friction noise between pads and rotors, braking efficiency decreases, especially dangerous during rain or downhill driving. With over a decade of driving experience, I've seen many similar cases where ignored noises led to roadside breakdowns requiring tow trucks. My advice: pull over immediately, turn off the engine, don't drive it, and preferably call a tow truck straight to the repair shop. Never skip routine maintenance – especially checking tires, bearings, and suspension before long trips, which prevents over 90% of risks. Safe driving is paramount – unusual noises are your car's warning signals. Don't wait for major disasters to regret inaction.

Last month, my rear wheel also made a strange noise, a buzzing sound that was really annoying. At first, I thought it was a minor issue, but after inspection, it turned out the bearing was completely damaged. A friend mentioned that this could cause the wheel to lock up, leading to the car fishtailing during emergency braking, which is quite scary. The reasons can vary—like a nail in the tire, uneven tread wear, loose suspension bolts increasing vibration, or issues with the braking system. Ignoring these can turn the noise into a serious malfunction, compromising driving stability and making the car prone to rollovers on bumpy roads. It's best not to risk driving; stop and check by gently shaking the wheel to see if it's loose, then get a professional diagnosis at a repair shop ASAP. Sharing this experience to remind everyone not to delay—safety first, and the earlier you address it, the less the damage.

Rear wheel noise can indicate potential hazards, and I need to explain clearly. Common causes include worn wheel bearings producing a humming sound, loose suspension components like links or shock absorbers causing a rattling noise, or misaligned brake discs increasing friction. These issues can disrupt the vehicle's balance, making it prone to rollovers or loss of control during emergency maneuvers or high-speed driving. Develop a habit of turning off the engine and checking whenever you hear unusual noises—don't wait for the problem to escalate. It's recommended to seek timely repairs to ensure safe driving.

As an ordinary car owner, I believe rear wheel noise should never be ignored. It often indicates serious issues, such as bearing failure that could suddenly lock the wheel and cause an accident, or brake system defects leading to vehicle rollaway when parked on slopes. When the noise worsens, handling becomes more difficult, especially dangerous in rainy conditions. I recommend immediately slowing down and stopping the car—don't force it to keep driving—then contact a 4S shop or roadside quick repair point to inspect the specific problem area. Regular maintenance can save you headaches: for example, check tire pressure and wheel fastening screws monthly, addressing any issues early to avoid bigger expenses.
