A friend, that is the widow of an American Legion passed buddy of mine, has a 2005 Tahoe LS and needs the driver's door hinge pins done and the same door lock actuator replaced. I have done the old style GMT400 and older hinge pins but never done the GMT800 pins. Looks pretty easy and the way to do it is to completely remove the door and then grind the heads off the pins. Am I gonna need a special tool to press the old pins out? Looks like the new ones just thread together. If need special tool, best place to get one?
