I have had trouble closingmy driver's side door since I've owned the car. I really have to slam it to get it to close and it is obviously not aligned because it leaks water when it rains and I can see daylight between the door and the weatherstripping. My uncle, my cousin, and myself have all messed with the striker, I obviously put door pins in too. The car was in an accident in the rear when it was new. If it is the door hinge on the body side, how difficult would it be to replace and make sure the alignment is correct with the door so it will seal and shut properly?
