Does the Langdong steering wheel cross shaft need lubricating oil?

[LaAlina]

Generally, the drive shaft does not require additional lubrication. There is a dust cover on the outside of the drive shaft, which is prone to damage after high mileage. Once damaged, the oil inside will leak out, so it should be replaced promptly. Usually, new covers are lubricated when installed. Function of the automotive cross shaft: The automotive cross shaft is used to transmit power at varying angles, serving as the 'joint' component in the universal drive system of a vehicle's drivetrain, where changes in the direction of the drive axis are needed. Reducing wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear on the parts, an oil film must be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear.
