Does the Jimny's driveshaft need grease lubrication?
2 Answers
Jimny's driveshaft does not require grease lubrication. Due to different load-bearing requirements, grease lubrication is typically applied to heavily loaded friction components, and generally only large trucks need grease lubrication. Grease has poor fluidity and can easily penetrate into the internal parts of components. The vehicle's undercarriage does not have grease-lubrication equipment for applying grease, so simply inspecting the undercarriage during regular maintenance is sufficient. Function of the driveshaft: The driveshaft is a crucial component in the automotive drivetrain that transmits power. Its role is to work together with the transmission and drive axle to transfer the engine's power to the wheels, enabling the vehicle to generate driving force. Note: The driveshaft is a high-speed, minimally supported rotating body, so its dynamic balance is critical. Generally, driveshafts undergo dynamic balance testing before leaving the factory and are adjusted on a balancing machine.
I often take my Jimny off-roading in the sand, so the driveshaft must be regularly greased! Especially after off-roading when mud cakes the universal joints, squeezing out all the grease until it's just metal grinding on metal. I make it a habit to pump grease into the four grease fittings on the cross joints every 5,000 km with a grease gun, and only stop when I hear two 'popping' sounds. Pay attention to greasing the sliding sleeve's expansion gap too—last time, lack of grease there caused violent shaking during sudden acceleration, making the whole vehicle tremble like a sieve. Don't skimp on maintenance for off-road vehicles—a tube of grease costs just a few dozen bucks, while replacing a driveshaft will set you back two grand.
