I think this answer was a little of the mark Not to disagree but the door opening all the way has nothing to do with the part mounted on the car but the inability to open comes from the bracket (slider) that goes in and out of the door and the hinges they sound like they are grinding when you open them if i read him right. Trying to re-align the door is not the answer and if you did have that problem(closing the door all the way) new hinge pins would be the best answer not trying to move the part on the body around that will make things worse I think?
