How do you replace a door hinge pin 1990 Chevy silvarado pickup?

Replacing a door hinge pin on a 1990 Chevy Silverado is a relatively straightforward job, but it can be a little fiddly. Here's how to do it:

Tools You'll Need:

* Punch (or drift punch): A slightly smaller diameter than the hinge pin is ideal. You want something sturdy enough to drive the pin out without bending.

* Hammer: A ball-peen hammer is best, but a regular claw hammer will work.

* Penetrating oil (like PB Blaster or WD-40): This will help loosen the pin if it's rusty or stuck.

* Grease: To lubricate the new pin.

* New hinge pin(s): Make sure you get the correct size and type for your Silverado.

Steps:

1. Preparation: Open the door fully. Spray penetrating oil generously onto the hinge pin(s) you're replacing. Let it soak for at least 15-20 minutes (longer is better if the pin is really stuck). This is crucial to prevent damage to the hinge.

2. Positioning: Find a suitable work surface, preferably one where you can safely lay the door down without scratching it. You might consider laying down a blanket or cardboard.

3. Driving out the Pin: Place the punch against one end of the hinge pin. Give the punch several firm but controlled taps with the hammer. Work carefully, and avoid striking the punch off-center. The pin should start to come out.

4. Persistence: If the pin is stubborn, apply more penetrating oil and try again. You may need to alternate between tapping on one end and then the other. Avoid using excessive force, which can damage the hinge.

5. Removal: Once the pin is mostly out, you might be able to pull it the rest of the way out by hand. If not, continue tapping gently until it's completely free.

6. Installation: Lightly grease the new hinge pin. Carefully insert it into the hinge. Use the punch to gently tap it into place until it's fully seated. Make sure the pin is straight and flush with the hinge.

7. Repeat: Repeat steps 3-6 for any other pins you need to replace.

8. Test: Once all new pins are installed, open and close the door several times to ensure smooth operation.

Important Considerations:

* Safety: Wear safety glasses to protect your eyes from flying debris.

* Multiple Pins: Truck doors typically have two or three hinges, each with a pin. You may need to replace multiple pins.

* Hinge Condition: Inspect the hinges while you're working. If they're badly damaged or worn, replacing them might be necessary.

* Pin Type: Some hinge pins are solid, while others are split. If you're replacing a split pin, make sure the replacement is the same type.

* Difficulty: If you're struggling, don't hesitate to seek help from a mechanic. Damaged hinges can be costly to repair.

By following these steps carefully, you should be able to successfully replace your Chevy Silverado's door hinge pins. Remember patience and precision are key!
