Always prioritize safety during vehicle maintenance. Failure to follow safety precautions may result in injury or damage to the vehicle.

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.

• Disconnect the vehicle's battery before starting any electrical work.
• If you are unsure about any step, consult a qualified automotive technician.
• Be aware that some original hinges may be welded, requiring specialized tools and techniques for removal.

4. Setup & Installation

This section outlines the general steps for replacing a door hinge. Specific procedures may vary based on your vehicle's make and model. Refer to your vehicle's service manual for detailed instructions.

Tools Required:

• Socket/Wrench Set
• Torx Bit Set (for some fasteners)
• Drill and Drill Bits (if original hinge is welded)
• Grinder (if original hinge is welded)
• Pry Tools / Trim Removal Tools
• Vehicle Jack and Jack Stands
• Penetrating Oil
• Masking Tape / Marker

Preparation:

1. Park the vehicle on a flat, level surface and engage the parking brake.
2. Disconnect the negative terminal of the vehicle's battery.
3. Open the door and support it securely using a floor jack with a padded surface or have an assistant hold it. This prevents the door from falling and causing damage or injury.
4. Carefully remove any interior trim panels or wiring harnesses that may obstruct access to the door hinges.
5. Mark the position of the existing hinge on both the door and the vehicle frame using masking tape or a marker. This will aid in proper alignment during reinstallation.

Installation Steps:

1. Remove Old Hinge: Loosen and remove the bolts securing the old lower door hinge to both the door and the vehicle frame. If the original hinge is welded, it will need to be carefully ground or drilled out. Exercise extreme caution and use appropriate safety gear.
2. Prepare Mounting Surface: Clean any rust or debris from the mounting surfaces on both the door and the vehicle frame. Apply a rust inhibitor if necessary.
3. Install New Hinge: Position the new Dorman 924-107 hinge onto the door and frame, aligning it with the marks made earlier. Loosely install the new mounting screws.
4. Adjust Door Alignment: With the screws loose, carefully adjust the door's position to ensure proper alignment with the vehicle body. Check for even gaps around the door and smooth opening/closing.
5. Tighten Fasteners: Once the door is properly aligned, tighten all mounting screws to the manufacturer's specified torque. Do not overtighten.
6. Reassemble: Reinstall any removed interior trim panels and reconnect wiring harnesses. Reconnect the vehicle's battery.

5. Operating Instructions

After installation, the door should open and close smoothly without binding or excessive effort. The hinge is designed to maintain the door's position when open and provide proper support during movement.

• Test the door's full range of motion, ensuring it opens and closes completely.
• Verify that the door latches securely when closed.
• Check for any unusual noises or resistance during operation.

6. Maintenance

Regular maintenance can extend the life of your door hinge and ensure continued smooth operation.

• Lubrication: Periodically apply a small amount of automotive-grade grease or lubricant to the hinge pins and moving parts to prevent wear and reduce friction.
• Inspection: Routinely inspect the hinge for signs of wear, rust, or damage. Check that all mounting bolts remain tight.
• Cleaning: Keep the hinge area clean from dirt and debris that could interfere with its operation.
