What are the causes of driveshaft noise?

[OliveAnn]

Reasons for driveshaft noise: 1. Excessive clearance caused by wear of the spline teeth sleeve connecting the transmission output shaft and the driveshaft; 2. Loose driveshaft universal joint bearings, which produce noise during acceleration, deceleration, and braking, and may even detach in severe cases; 3. Detached or unqualified dynamic balancing weights on the driveshaft, causing dull noises during high-speed operation. Daily maintenance methods for driveshaft: 1. Check if the spline teeth on the output shaft have become pointed, and replace the output shaft if necessary; 2. Replace the driveshaft spline teeth sleeve and driveshaft bearings; 3. Replace the driveshaft universal joint bearings or the entire driveshaft assembly.
