What Causes the Abnormal Noise in a Car?
1 Answers
The causes of abnormal noise in a car are as follows: Loose Suspension: If the car makes a squeaking sound when driving at low speed, it is likely coming from the suspension. 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. Brake System Malfunction: If the abnormal noise increases when stepping on the brake, it can be confirmed that there is an issue with the brake 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 brake system, mainly manifesting as sharp and continuous sounds. Loose Engine Belt: This can also cause a squeaking sound. You can try pinching the drive belt with your fingers and twisting it. Note that this operation should be performed when the engine is cool, and the twisting angle should generally be below 90 degrees. Otherwise, the tension should be adjusted. Aging Components: This situation may occur in areas with rubber parts, especially the engine mount cushions. If they become hardened or cracked due to aging, it can lead to increased car vibration, shaky steering wheel, and louder noise.
