What Causes Squeaking Noises While Driving a Car?

[StCooper]

Causes of abnormal noises while driving a car: deformed exhaust pipe; abnormal engine. Deformed Exhaust Pipe: In most front-engine vehicle models, the exhaust pipe extends from the undercarriage to the rear of the car. Driving on rough roads or impacts to the chassis can easily cause the exhaust pipe to dent and deform. A deformed exhaust pipe increases exhaust resistance, leading to abnormal noises. Abnormal Engine: This is mainly caused by excessive wear of certain parts or improper assembly and adjustment. Some abnormal noises can serve as warnings, while engine noises may indicate impending serious damage. Therefore, when the engine produces abnormal noises, it should be repaired promptly to prevent further damage.
