Let's get this over with before you say it. You should not have been backing up with the door open. When backing out of my garage, the driver's door caught the grass catcher on my riding lawn mower. The impact tried to open the door too far. There is no visible damage, but now when the door is shut it makes a grinding/clunking noise. The door still shuts and locks properly. I think I can fix the problem with an adjustment to the hinges and/or the latch. How do I go about making these adjustments? TIA
