Tools You'll Need:
* Punch: A slightly smaller diameter than the hinge pin is ideal. You might need a few sizes to find the best fit. A ball-peen hammer is useful here.
* Hammer: A standard hammer for tapping the punch.
* Penetrating oil (like PB Blaster): Crucial for loosening rusted pins.
* Wire brush (optional): To clean off any rust or debris around the hinge pins.
* New hinge pins: Ensure you get the correct ones for your S10's year and model.
* Gloves: Protect your hands.
* Jack stands (recommended): To safely support the door while working. A helper can also hold the door.
* Cloth or rag: To clean up any mess.
Steps:
1. Preparation: Open the door fully. Apply penetrating oil liberally to each hinge pin. Let it soak for at least 15-30 minutes (or longer if heavily rusted). This is the most crucial step for avoiding damage.
2. Support the Door: Use a jack and jack stands to support the door's weight. Alternatively, have someone hold the door securely. Never work under a door supported only by the hinges.
3. Remove the Hinge Pins: Use the appropriately sized punch to tap out the hinge pin. Start by tapping gently from one side. If it's stuck, apply more penetrating oil and try again. You may need to alternate tapping from each side. Work slowly and carefully to avoid damaging the hinge. The pin should come out from the top hinge first.
4. Clean the Hinges: Use a wire brush to clean the hinges and the hinge pin holes. Remove any rust or debris.
5. Install the New Hinge Pins: Insert the new hinge pin into the top hinge. Gently tap it in with the hammer and punch. Once it's partially in, you may be able to push it the rest of the way by hand.
6. Repeat: Repeat steps 3-5 for the remaining hinge pins.
7. Test: Close and open the door several times to ensure it operates smoothly.
Important Considerations:
* Rust: If the pins are severely rusted and won't budge, you might need to use more aggressive methods, such as a rust removal tool or even drilling out the pin (as a last resort). Be extremely careful when drilling.
* Bent Pins: If the pin is bent, you may have to carefully straighten it before removal. If it's severely bent, replacement is recommended.
* Door Alignment: After replacing the pins, you may need to adjust the door alignment. Consult a repair manual or a qualified mechanic for assistance.
Safety First: Always prioritize safety. Use proper jacking and support techniques. If you are uncomfortable performing this repair yourself, it is best to take your vehicle to a qualified mechanic.
