Just greased my propeller shaft today. Please correct me if I'm mistaken, lithium grease on the spiders (universal joints) and molybdenum disulfide on the cardan joint and the slide yoke. How many grease fittings are there on the propeller shaft? I only seen 6. How would you know when to stop pumping grease in the slide yoke fitting. I did not see any grease coming out after pumping 20X.
