28-Jul-2012 Bill and I spend a Saturday in the stop away from the triple-digit heat we are having and re-assemble the lift with the new nuts. Each screw has also been well slathered in "open gear grease" that is infused with Molybdenum. It stinks a little bit and the lable on the can warns about prolonged skin contact because it will 'defat skin'. Yikes! After the drive system is reassembled, Bill and I spend the better part of an hour re-leveling the lifting beams.
