"Also, as for that rubber stopper...I worked on big rig trailers before I joined the military. The trailers that we worked on mostly use an oil bath bearing lube system. The outer rubber cap comes off, you pour oil in, and replace the cap. In the 18 months I worked on those trailers I had at least 15 or more trailers come in missing rubber caps and bearings going bad because of contamination. While no system is perfect, I would rather trust the metal cap that I knock on with a mallet versus a rubber stopper that can pop off when the bearing grease (or oil in the case of the big trailers) heats up and creates a pressure inside the hub/bearing area."
That "rubber stopper" is not to keep any grease or as you call it "oil" in. It is just a dust cap to keep road scum, etc from getting on the grease fitting.
I like the rubber cap for it's purpose
