You probably don't need to change the pins, just the bushings (unless you let the bushings wear through to the pins). If you need to replace the pins (or bushings), first you need a stool or crate (to set the door on) or someone to help you, since the door is surprisingly heavy. Next, hammer a tap (or a Flathead screwdriver) onto the bottom of the pin until it is free (falls out). You may need a Flathead screwdriver or chisel to pry the bushings out of the hole Replace the pin and bushings. Check the pins for wear, and if there is none, put them back. It seems like an ordeal, but it is actually pretty mechanical and simple.

There are three main types of door hinge pins available in the market: removable hinge pins, fixed hinge pins, and loose pin hinges. Removable hinge pins can be easily taken out for door removal or maintenance. Fixed hinge pins are permanently attached to the hinge and cannot be removed. Loose pin hinges have a pin that can be easily removed for door installation or removal.
To change the door hinge pins on a 1999 GMC Jimmy SLS, first, support the door with a jack or a helper to prevent it from falling. Remove the door panel if necessary for better access, then use a hammer and punch to drive out the old hinge pins from the hinges. Install the new hinge pins by aligning them correctly and tapping them in gently with a hammer. Finally, reattach any removed parts and check the door alignment and operation.
Because the hinges are welded in place, replacing the hinge pins and bushings should restore the door back to original position.
there is a bushing kit you can get because the pins don't go, the bushings do. all you need is a hammer, regular screwdriver, and some white lithium grease so it doesn't happen again you can buy these at any parts store and come with the bushings and pins
