Very helpful, thank you! That makes sense. I had to do an image search for "zerk fitting." :-) It's not up right now (stored in my parent's driveway 40 miles away until I find a permanent home for it closer to me) but I'll make sure to do this the next time I open it.

Drawing too many amps because of the effort to lift, probably due to too much friction that the silicon spray and grease will likely alleviate?
