Still using SAE 140. A couple more blobs of grease appeared, and then nothing from the top of the column after that. I suspect that the worm in the box acts like an Archimedes screw, winding the grease up the column on the one lock but doesn't drag it back on the other. Result: the grease fills the column and is forced out at the top.
