Why spline lubrication?
« on: November 19, 2025, 04:11:56 AM »
Especially BMWs seems to require spline lubing of the clutch shaft splines as well as final drive splines. But we never hear this about cars. Well, at least I do not. Anybody know what this is required (more) on bikes than cars?

One thing is that automotive driveshaft splines are in an oily environment

 The lube is more to inhibit corrosion than to provide lubrication.
