What are the reasons for loud noise while driving?
2 Answers
Vehicle driving loud noise main reasons are as follows: 1. Excessive tire pressure causing abnormal noise. During daily use, tire pressure should be adjusted within the standard range (generally 2.3bar-2.5bar). If the tire pressure is too high, it will cause severe wear on the tire crown, reduce the tire's shock absorption and cushioning performance, and significantly increase tire noise. 2. Abnormal tire wear causing abnormal noise. The tire crown contacts and rubs against the ground. If the tire crown wears unevenly with bumps, it will produce a buzzing sound. 3. Wheel hub bearing damage causing abnormal noise. Worn wheel hub bearings will produce noise, mainly due to long-term use causing wear and looseness. During daily use, avoid violent impacts on the wheels and prolonged wading to protect the wheel hub bearings.
I've been driving for almost 20 years, and loud noises are usually caused by the engine or tires. When there's too much carbon buildup in the engine, it runs unevenly and makes a whining sound; if the engine oil is too low or old, friction increases, and the noise follows. Tires are another major culprit—for example, worn treads or insufficient tire pressure can cause a humming noise on uneven roads. Aging suspension systems are even more annoying, creaking like old furniture falling apart when going over speed bumps. If you don't fix it, not only is it noisy, but fuel consumption can also spike by about 10%. Last week, I encountered a hissing sound from an exhaust leak—fixing a small hole solved the problem. I recommend doing a simple check every 5,000 kilometers. A routine maintenance service costs just a couple hundred bucks, which is much cheaper than repairing major components.
