In the Toyota model, the drive shaft and the output shaft using spline connection, and bolt connection is different, when the rear wheel up and down when the bump or wheel movement state changes, the drive shaft on the spline slip sleeve connector to allow the length of the drive shaft Make the appropriate change.
    When the drive shaft slip jacket too much oil or too little, the problem appeared. Especially in snow and saline areas, inappropriate maintenance will make spline corrosion and adhesion. On the other hand, in the refueling do not pay attention, may be too much oil into the drive shaft slip hook near the mouth of the mouth. The excess lubricants can stick the slip joints together, and the results are as if they are corroded.
    An adhesive shaft is like a bad universal joint, which can cause the drive shaft to produce a vicious vibration that is sensitive to speed. When the car accelerates from the standstill, the drive shaft that can not slide is usually caused by the feeling of the vehicle, the percussion or the shock of the drive shaft.
    If you suspect that the oil is excessive, remove the bolts at one end of the drive shaft, remove the grease nozzle, and patiently withdraw the excess lubricant from the joint. If the grease is not easy to remove, the two parts of the drive shaft with self-chalk made reference to the assembly mark, and then pull the drive shaft slip joints, the spline maintenance.
