Tools You'll Need:
* Punch: A well-fitting punch (slightly smaller than the pin diameter) is crucial. A tapered punch is even better as it helps to start the pin moving. Avoid using a screwdriver, as it can damage the pin and hinge.
* Hammer: A ball-peen hammer is ideal, but a regular hammer will work. Use a smaller hammer if you're concerned about damaging the hinge.
* Penetrating oil (PB Blaster, WD-40, etc.): This is vital for loosening rusted pins. Apply liberally and let it soak for at least 30 minutes, or even overnight if the pins are severely rusted.
* Vice grips (optional but helpful): If the pin is stubborn, vice grips can help grip the pin while you're driving it out.
* New hinge pins: Make sure to get the correct replacement pins. Your local auto parts store should have them.
* Grease: Use a good quality grease to lubricate the new pins before installation.
* Wire brush (optional): To clean out any rust or debris from the hinge.
Steps:
1. Preparation: Open the door to the widest possible angle. This will give you the best access to the hinge pins. Apply penetrating oil generously to each hinge pin. Let it soak. Reapply as needed.
2. Removing the Pins: Position the punch against the end of the hinge pin. Use firm, consistent taps with the hammer. Work the punch gradually, avoid forceful blows that could damage the hinge. If the pin is particularly stubborn, use the vice grips to grip the pin while you tap it out.
3. Cleaning: Once the pin is removed, use a wire brush to clean out any rust or debris from the hinge.
4. Installation: Lightly grease the new hinge pin. Carefully insert the new pin into the hinge. Start by inserting one end and then gently tap the other end in with the punch and hammer. Be careful not to damage the hinge.
5. Repeat: Repeat steps 2-4 for each hinge pin on the door.
6. Testing: Once all the pins are replaced, open and close the door several times to ensure smooth operation.
Important Considerations:
* Rust: Rust is the biggest enemy here. The more time you allow the penetrating oil to work, the easier the process will be. If the pins are severely rusted and broken, you may need to replace the entire hinge.
* Patience: This is not a quick job, especially if the pins are rusted. Be patient and persistent. Avoid using excessive force.
* Safety: Wear safety glasses to protect your eyes from flying debris.
