Door Hinges
A Camaro door weights upwards of 200 pounds. They're heavy and they put a
strain on the hinges over the course of the years. Eventually, your door will
not want to shut correctly.
To test or check your hinges, open the door and try and wiggle the door. The
door shouldn't wiggle but try and lift the car up.
If your door doesn't want to shut, or is tough to open, the easiest thing to do is check the alignment of the striker.
