Tools You'll Likely Need:
* Correctly sized ignition key: This is crucial. A damaged or incorrect key could cause further problems.
* Small flathead screwdriver: For prying and manipulating small parts.
* Phillips head screwdriver: Potentially needed for screws holding the steering column shroud.
* Needle-nose pliers: For reaching small parts and potentially manipulating retaining clips.
* Socket set: Might be needed depending on the specific retaining method.
* Ignition switch removal tool: A specialized tool is available that simplifies the process by providing proper engagement points and preventing damage. This is highly recommended. Search for "Ford ignition switch removal tool" to find options.
General Steps (These are guidelines, consult your repair manual!):
1. Steering Column Removal (Possibly): In some cases, you might need to partially or completely remove the steering column shroud to gain access to the ignition switch. This usually involves removing screws and carefully working around the steering column. Be very cautious not to damage the wiring harness.
2. Disconnect Battery: Disconnect the negative (-) battery terminal to prevent short circuits.
3. Remove the Steering Column Shroud (If Necessary): Once the shroud is off, you should have better access to the ignition switch.
4. Locate the Ignition Switch: The ignition switch is usually located behind the steering wheel, and the lock cylinder is the part that the key goes into.
5. Ignition Switch Retention: The method of retaining the lock cylinder varies. It might be held in place by:
* A retaining clip: This often requires carefully prying or using a small tool to release the cylinder.
* Screws: You might find small screws securing the cylinder to the ignition switch housing.
* A retaining ring: This may require specialized tools for removal.
6. Remove the Lock Cylinder: Once you've identified and released the retaining mechanism, gently pull the lock cylinder out. It may be slightly tricky and require some maneuvering. Again, a specialized tool is extremely helpful here.
7. Installation (Reverse of Removal): When installing a new cylinder, ensure proper alignment and secure all retaining mechanisms before reassembling.
Important Safety Considerations:
* Wiring: Be extremely cautious around the wiring harness connected to the ignition switch. Avoid pulling or damaging the wires.
* Airbag: If your vehicle has an airbag, take extra precautions to avoid deployment. Disconnect the battery and follow any specific safety instructions in your repair manual.
* Steering Wheel Lock: The steering wheel lock may engage during the process. Carefully work around it.
Disclaimer: This information is for guidance only. Improper removal can damage your vehicle's electrical system or steering column. Always consult a repair manual specific to your 1973 Ford Bronco for detailed instructions and safety precautions. If you are uncomfortable performing this repair yourself, seek the help of a qualified mechanic.
