how are you.
has it been hit or in an major prang , or has the door rubbers gone, and not for getting the pivet on the hinges on which the door sit,s is that all all lose and cactus,
it could be heaps of things
if the piller post is bent , or hinges worne out , or door is strected and busted at the hinge
the door striker moved on the centre piller
I under stand your after a process in alignment but if
A , is stuffed then
B , has no point
or you could just grab the bottom of the door at the back and give it a heve ho,
just a thought some one else will probly no more.
