after days in the past of trying to line up doors i got so bored of the old methods holding up tightning and loosening top and bottom and all, then finding out the hinges are worn, simple mothod that works

use a small trolly jack on the inside floor with a prom up to the door catch brackety thing and jack with all bolts loose, so it lifts it adjust the jack hight to were you want it and then tighten up the bolts from the bottom up, bloody hell its easyer, just thought id say to all the people who have saggy doors.
