How do you change door pins on a 2005 Chevrolet Avalanche?

To change the door pins on a 2005 Chevrolet Avalanche, first, remove the door panel to access the hinge area. Then, support the door with a jack or a helper, and use a punch or a similar tool to drive out the old pins from the door hinges. Insert the new pins into the hinges, and ensure they are properly aligned. Finally, reattach the door panel and test the door to ensure it swings smoothly.
