Tools You'll Likely Need:
* Appropriate sized screwdrivers: Phillips and possibly flathead. The exact size will depend on your car.
* Ignition switch removal tool: While not strictly necessary, a specialized tool makes the job much easier and reduces the risk of damage. These are available online or from auto parts stores.
* Needle-nose pliers: For reaching small parts.
* Penetrating oil (like PB Blaster): To loosen any seized screws or parts.
* Shop rags: To keep things clean.
* A service manual for your specific 1970 Dodge Challenger: This is highly recommended. It will have diagrams and detailed instructions.
General Steps (Consult your service manual for precise details and diagrams):
1. Disconnect the battery: This is crucial to prevent accidental shorts and damage to your electrical system.
2. Remove the steering wheel: This is usually a multi-step process involving removing the horn connector, nut(s) securing the wheel, and possibly a retaining plate. You will likely need a steering wheel puller tool for this. Mark the steering wheel's position relative to the steering column before removing it to ensure proper realignment.
3. Access the ignition lock cylinder: Once the steering wheel is off, you'll have better access to the ignition switch housing. This typically involves removing some screws or fasteners holding the ignition switch shroud or bezel in place. The location and type of fasteners vary by model.
4. Remove the ignition switch housing: This part may require careful prying or the use of special tools. Take your time and avoid forcing anything. The housing might have some electrical connectors that need to be disconnected first.
5. Remove the ignition lock cylinder: This is where a specialized ignition switch removal tool is highly beneficial. The cylinder is typically held in place by a retaining clip or pin that needs to be carefully manipulated or removed. This is the trickiest part of the process. Some cylinders might require a special key or jig to be removed. Your service manual will provide the correct procedure for your model.
6. Reinstallation: Reassembly is the reverse of the removal process. Ensure all parts are properly aligned and securely fastened. Pay particular attention to reconnecting any electrical connectors. Make sure the ignition switch functions correctly.
Important Considerations:
* Replacement cylinder: If you are replacing the ignition lock cylinder, ensure you get the correct one for your specific 1970 Dodge Challenger model.
* Key: You'll need the key to the ignition cylinder to turn it to the correct position for removal.
* Security: Be aware of the security implications of replacing or removing the ignition cylinder. This could affect your vehicle's anti-theft system if it has one.
Strongly Recommended: Again, I emphasize the importance of obtaining a service manual for your specific 1970 Dodge Challenger. It will provide accurate diagrams and detailed instructions to avoid damage to your vehicle. If you're not comfortable performing this repair yourself, take your car to a qualified mechanic. This job is complex and improperly done can cause significant damage.
