Why the cross shaft of the drive shaft universal joint will sound


Imported car drive shaft universal joint cross shaft mostly solid shaft, the result can reduce the size, enhance the stiffness and strength, but can not set the nozzle, can not be lubricated in maintenance. When the vehicle travels longer, the cross shaft is broken by the lack of grease to the needle roller bearings, the cross shaft and the bowl are ablated and produce abnormal sound. Which is characterized by when the vehicle at low speed, in the lower part of the body to hear a dry friction creak sound, as if the generator bearing dry oil dry friction, clear and simple, rhythmic.
