It’s just a fact of life; things sag as they get older. Just ask the owner of a classic car how hard they have to slam their doors if you need proof. After years of use and abuse, the bushings in the hinges are wallowed out and are allowing the door to drop down several millimeters, even in Corvettes with lightweight fiberglass door shells. While it’s not particularly complicated job to repair the hinge bushings in a Corvette, it can be time consuming and frustrating if you don’t quite know what you’re doing. Luckily, this awesome video from YouTube shows you step-by-step how to replace the worn out door hinge bushings in your C3 Corvette.
Unfortunately, with the C3 Corvettes it’s not quite as easy as having someone hold the door up while you knock the hinge pins out, because the body work will block the pin from being able to completely pull out of the hinge. So, first you’ll need to remove the door itself from the hinges by loosening the 4 bolts per hinge that lie behind the door panel that hold the door on the hinge. Once you have the door freed from the hinges and supported, you can start trying to knock loose the hinge pin; just be aware that you might still need to cut a “D” shaped notch in the top of the pin to get it to clear the fender.
