I use Dri-Slide. It is molybdenum in a rapidly evaporating carrier. First extend the front jacks almost all the way and clean them to remove dirt, old grease and oil, etc. I never use grease or oil because it attracts road dirt and grime. The jack gears should be lightly coated with - naturally- gear and sprocket lube. I use the spray kind for convenience.
