What Causes the Driveshaft to Make a Buzzing Noise?
1 Answers
Driveshaft buzzing noise may be caused by an unbalanced driveshaft. The symptom of an unbalanced driveshaft is a periodic noise heard while the car is moving, which becomes louder as the speed increases. In severe cases, it can cause the car body to shake, and the driver may feel numbness when holding the steering wheel. The driveshaft is an important component in the automotive drivetrain that transmits power. Its function is to work together with the transmission and drive axle to transfer the engine's power to the wheels, generating driving force for the car. The driveshaft is composed of a shaft tube, a telescopic sleeve, and universal joints. The telescopic sleeve automatically adjusts for changes in the distance between the transmission and the drive axle, while the universal joints ensure the angle change between the transmission output shaft and the drive axle input shaft, achieving constant angular velocity transmission between the two shafts.
