Abnormal noises from the car chassis may be abnormal noises from the car's suspension. The suspension system of a car generally includes upper and lower swing arms, balance bars, ball head shock absorbers, etc. Generally, the abnormal noise caused by the suspension system is a relatively dull or crisp impact sound. For example, after the balance rod tie rod is damaged or the bushing is worn, a continuous abnormal sound of "Gluggler" will be emitted when passing through bumpy roads.

If the vehicle makes such abnormal noises, it is best to have it repaired as soon as possible. Damage to the suspension system will lead to direction deviation, tire damage and other consequences.

It is also possible that the constant velocity universal joint is commonly known as the ball cage, which is divided into an inner ball cage and an outer ball cage. If the vehicle makes an abnormal sound similar to "clack, clack, clack, clack" while turning, it is usually caused by serious wear of the constant velocity joint. You only need to confirm which side the abnormal sound is from, and then replace the constant velocity joint. The joint can be solved.

Abnormal noise from car bearings. No matter how big the tire is on a car, the connection between the car body and the tire relies on a small wheel core bearing. If the wheel core bearing is damaged, the vehicle will make a continuous abnormal sound similar to "buzzing" when driving. The faster the speed, the stronger the sound. , if the bearing is slightly damaged, there will usually be abnormal noise when turning lightly. Severe damage to the bearings will cause the tires to run off track, and severe tire wear will cause the tires to fall off.

Abnormal noise from the exhaust pipe generally manifests itself as a "puff-puff-puff" noise after the vehicle is started, and the gas pedal makes a roar similar to that of a sports car. In this case, the exhaust pipe is usually ruptured or leaking. caused.

The above are the more common abnormal noises in the car chassis. If the vehicle has the above abnormal noises, it must be repaired and replaced as soon as possible.

Abnormal noises in cars are inherently difficult to deal with. After all, a car is composed of tens of thousands of parts, and there are many causes of abnormal noises. Therefore, in specific cases, it is necessary to go to a repair shop for detailed inspection
