When I open my drivers door, it stops at the first hitch which is kind of halfway, and then I have to push hard to open the door all the way to get in coomfortably. Where do I grease to get this thingy working smoothly? Do I have to take of the door? This is more important for my wife, any ideas? Thanks.
