Hello,

I'm not sure but I would think that it would be the adjustment screw since it is inside the door. When adjusting the screw, I would recommend taking the weight off the door to help with the adjustment. You could also have someone help hold it up or use a pry bar to lift the weight off the wheel. Thanks for posting and let us know if you have any other questions.
