The driver side door on my Ranger has a large gap between the rear edge of the door and the cab. Also, the front edge of the door actually rubs the front fender. It looks to me like I will have to remove the front fender in order to loosen the door to the point that I can adjust it and get the gaps right. Is this right, and if I do have to remove the fender, how difficult is it? Thanks in advance for your help.
