OK ... I give up. Somebody please help me out. My front doors on my 1978 Suburban are driving me crazy. I have replaced all 4 hinge pins and bushings but they still won't close right unless I SLAM them shut. If I don't SLAM them then they only partially latch (door rattles and looks like it's going to open) I have tried moving the striker post and the hinges around but I can't seem to get them lined up to work properly AND seal out the elements. Can anyone give me some simple tricks/hints to align the doors so that they will close properly?
