Roughness/Vibration
If the driver is noticing vehicle vibration or roughness at any speed, the problem can be caused by a dented, bent or off-balance driveshaft, which should then be serviced. Vehicle roughness or vibration also may be caused by worn U-joints, which also can be serviced, or loosened U-joint clamp bolts, which can be tightened to correct the issue.Drivelines may produce a noticeable knocking noise, which typically is caused by damaged or worn universal joints in the drive shaft. This problem can be detected by disassembling and inspecting the universal joints. If wear or damage is discovered, the U-joint assembly should be replaced.
Pinging/Snapping
Pinging or snapping sounds emanating from the driveline are caused typically by loose upper or lower control arm bushing bolts, or loose double Cardan mounting bolts. If loose, these bolts can be tightened to the specified torque to correct the problem.
Handle shafts repay torque and rotation, on the contrary can develop problems.Drive shafts refer to mechanical components that connect elements of a drive train, and transmit rotation and torque. Drive shafts can develop problems that can impair vehicle operation.Knocking
