My Fulton Jack on my 2010 puma ftd stopped extending far enough to get it off of the ball of my truck. once it gets to a certain point the handle just spins and the jack no longer extends. It will work at the lower end just not high enough to get it off of the truck. It worked just fine until a few weeks ago. I am unfamiliar with the inner workings of these jacks to know if they are worth taking apart to try and repair. Anyone know or do I just need to get a new one?ThanksAaron
