What are the symptoms of a broken car driveshaft?

[LaJohnny]

Symptoms of a broken car driveshaft: 1. A clunking sound when starting or accelerating sharply, with a feeling of loose mechanical parts; 2. A buzzing sound from the chassis while driving, which becomes louder as the speed increases; 3. Severe damage can lead to inability to drive, as well as phenomena such as veering off course and severe shaking. If these symptoms occur, the vehicle can be taken to a repair facility to check whether the driveshaft's working clearance is normal and whether the dynamic balance has failed. The driveshaft is a crucial component in the car's drivetrain that transmits power, working together with the gearbox and drive axle to transfer the engine's power to the wheels, generating driving force for the car. The driveshaft is a high-speed, minimally supported rotating body, making dynamic balance very important. Generally, driveshafts undergo dynamic balance testing before leaving the factory and are adjusted on a balancing machine.
