How do I adjust driver side door on 2002 Chevy Silverado 1500
First thing to check is the door hinge pins for wear, open the door wide enough so you can grab onto the door and see if you have any up and down movement if you do that has to be fixed first before you attempt to adjust the striker pin.
don't move the striker on the post until you fix the bushings on the hinge, then if it needs to be adjusted measure from the ground up to the center of the pin then do the same for the clasp on the door this will get you close then lightly snug the pin and close the door note if the pin moves up or down and make the adjustment slowly
