To install door pins on a 2001 Bravada, first, ensure the door is fully open. Remove the old pins if necessary by using a punch to drive them out. Align the new pins with the hinge holes, then gently tap them in with a hammer until they are fully seated. Finally, test the door movement to ensure it operates smoothly.
You replace The hinge pins
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.
The old door hinge pins have to be cut out with a torch on a 1989 F-150. Then, new hinge pins can be welded into place. This part might be available at an automotive salvage yard for a fraction of the cost of new hinges.
