If anyone out there has one of these trailers or a bent and busted jack I would love the have the nut that travels up and down the screw to take the foot up and down. I have a jack that is in great shape except for that part. I tore it down and its not hard to get into. my jack that one part is broken. I even got the bent pins straightened and the jack is working again but I would really like to make it full strength again.
