What Causes Driveshaft Noise?
1 Answers
Driveshaft noise is usually caused by bending or denting of the driveshaft, which creates imbalance during operation, leading to wobbling and noise. Additionally, improper installation of the driveshaft, such as the universal joint forks at both ends not being aligned on the same plane, or the original balance weights not being reinstalled in their original positions, can disrupt the balance. Loose connecting bolts of the universal joint coupling, or loose fixing bolts of the driveshaft center support can also result in driveshaft noise. The solutions for driveshaft noise are: 1. Start the car engine and engage a high gear to observe the driveshaft wobble. If the wobble is most pronounced when the RPM decreases, it indicates the noise and wobble are caused by imbalance. Otherwise, the noise is due to looseness. 2. If the noise is not severe, the vehicle can be driven back for repairs. If severe, stop the vehicle immediately for repair.
