Tools You'll Need:
* Punch: A selection of punches, including a small, tapered punch and possibly a slightly larger one. The tapered punch is crucial for gently driving out the hinge pin.
* Hammer: A ball-peen hammer is ideal, but a regular hammer will work. Avoid using excessive force.
* Penetrating Oil (like PB Blaster or Liquid Wrench): This is vital for loosening rusted pins.
* New Hinge Pins and Bushings: Make sure you get the correct ones for your S10's year and model.
* Grease: A good quality lithium grease.
* Wire Brush (optional): To clean up any rust or debris.
* Clamp (optional): To hold the door in place while working.
* Socket Wrench and Sockets (optional): Some S10s might require removing screws to access the hinge more easily, depending on the design.
Steps:
1. Preparation: Park your S10 on a level surface and engage the parking brake. Apply penetrating oil liberally to the hinge pin. Let it soak for at least 30 minutes, or even overnight if the pin is severely rusted. Reapply as needed.
2. Access the Hinge Pin: You'll likely need to work from the inside of the door. Locate the hinge pin (it's the metal pin that runs through the hinge).
3. Remove the Hinge Pin: Use the small, tapered punch to gently tap on one end of the hinge pin. Work slowly and carefully. If it's stubborn, apply more penetrating oil and let it sit. Tap the punch around the circumference of the pin to help break it loose. Once you've started it, you may be able to use your fingers to finish pulling it out. If not, continue using the punch. Avoid hammering too hard; you risk damaging the hinge.
4. Remove the Old Bushings: The bushings should come out relatively easily once the pin is removed. If they're stuck, use the punch to gently tap them out.
5. Clean the Hinges: Use a wire brush to clean any rust, dirt, or debris from the hinge and the hinge mounting areas.
6. Install the New Bushings: Carefully press the new bushings into place. Make sure they're seated correctly.
7. Install the New Hinge Pin: Lightly grease the new hinge pin. Insert it into the hinges, ensuring it's aligned properly.
8. Tap the Pin in Place (if needed): You might need to use a punch to gently tap the hinge pin back into place, but it should go in fairly easily if the bushings are installed correctly. Don't force it.
9. Lubrication: Lubricate the hinges generously with grease.
10. Test the Door: Open and close the door several times to ensure it operates smoothly.
Important Considerations:
* Safety First: Always use caution when working with tools. Wear safety glasses to protect your eyes.
* Patience: This is a process that requires patience. Don't rush it, or you risk damaging the hinges.
* Stubborn Pins: If the pin is extremely rusted and refuses to budge, you might need to consider using a hinge pin removal tool, available at auto parts stores. In some extreme cases, replacing the entire hinge assembly may be necessary.
If you're uncomfortable performing this repair yourself, it's always best to take your S10 to a qualified mechanic. This process is relatively simple, but requires some mechanical aptitude.
