To change the front door hinge on a 1991 Mercury Grand Marquis, start by supporting the door with a jack or a helper to prevent it from falling. Remove the hinge bolts using a socket wrench, starting with the door side and then the body side. Once the old hinge is removed, install the new hinge by aligning it properly and securing it with the bolts. Finally, test the door for proper alignment and operation before fully tightening the bolts.
