When the car is running, the drive shaft generates vibration and transmits it to the body, which causes the body vibration and noise. Its vibration is generally proportional to the speed of the vehicle.1, the clicking noise or vibration when turning is usually due to the wear or damage of the external constant speed universal joint. When checking the appearance of the drive shaft, check whether the outer uniform speed universal joint sheath is damaged. If the sheath is damaged, pollutants such as dust and sludge will damage the lubrication and cause early damage to the universal joint, and the constant speed universal joint will not operate smoothly, causing vibration.
Starting vibration refers to the shaking phenomenon felt in the steering wheel or the front of the vehicle when the vehicle gradually accelerates from a standstill. When the vehicle accelerates, the initial tremor is also manifested as the vehicle rocking back and forth. The conditions that lead to a shaky start in a front-drive vehicle are wear or damage to the inner three-column grooved universals, excessive coupling internal angles and faulty engine/transmission mounts. Coupling Angle is often too large due to the front tilt head or spring height adjustment is too high.
Power system installation seat damage or improper adjustment will also produce coupling Angle is too large and cause start vibration. During rapid acceleration, the height of the front suspension increases due to excessive torque of the vehicle power system, excessive wear of the coupling, or the Angle of the inner three-column slot universal joint increases during acceleration, which leads to starting vibration. If the above problems have been eliminated and there are still turning sounds or start jitter, please check the following parts:
① Slip with the spline in the CV Joint.
② the drive shaft produces bending or torsional deformation.
③ the connecting parts are loose, or the rubber balance block is offset.
④ transmission output shaft spline teeth wear seriously.
⑤ the internal wear of the direction machine is serious, and the gap is too large.
⑥ the booster pump is damaged
⑦ Steering ball head or cantilever CV Joint damaged
⑧ Triangle arm bushing wear seriously
⑨ the connection part of the drive shaft is loose.
