I have the same doors (sounds like it) and so have been messing with them here. I finally asked hubby how he does it. He showed me that he does it by pushing UP on the door to lift the wheel out of the track and then tipping the door in or out. Also, mine have the wheel bracket screwed on at the inner top of the doors and hubby says that loosening the screws is another way to remove them if the doors are too high to the ceiling to be able to push up.

Good luck
