What are the reasons that cause the cross shaft of the 3102-2201025 Russian universal joint cross to make a noise during operation? What should I do if there is a noise on the cross shaft?Because the structure of the cross shaft of the universal joint is solid, there is no oil nozzle to add lubricating oil, and the mentality of not being able to dismantle indiscriminately, resulting in serious wear and friction, so replace it with a new one. When there is a slight noise, disassemble the cross shaft, remove the circlip, the cross shaft and the steel needle, clean and apply lubricant to continue using. It can only be replaced if the damage is severe.The noise of the universal joint shaft may also be caused by the lack of a grease nipple device and timely maintenance. After a period of use, it should be disassembled and greased in time.Small universal joints are used to transmit motions that are not on the same axis.
