Here's a general outline; however, this is NOT a substitute for a detailed repair manual specific to your 1984 CJ7:
1. Safety First: Disconnect the negative battery terminal before starting any work on the electrical system.
2. Steering Column Removal (Potentially Necessary): Depending on the specific model and modifications, you might need to partially or fully remove the steering column. This involves removing the steering wheel, column shroud, and potentially other components. This is a complex step and requires careful attention to detail and potentially specialized tools. Consult a repair manual for your exact model.
3. Access the Ignition Lock Cylinder: Once you have access to the ignition switch, you'll see the ignition lock cylinder itself. This typically involves removing screws or retaining clips holding the ignition switch assembly in place.
4. Remove the Ignition Lock Cylinder: This involves carefully removing the cylinder. There's usually a retaining clip or a small screw holding it in place. A special tool might be needed to remove the cylinder without damaging it. Some cylinders use a retaining ring; a small flathead screwdriver, or a specialized tool will be needed to gently pry this back.
5. Install the New Ignition Lock Cylinder: Once the old cylinder is removed, carefully install the new one. Make sure it's correctly seated and securely fastened.
6. Reassemble: Carefully reassemble all components you removed earlier, including the steering column (if removed) and the steering wheel. Make sure everything is properly aligned and securely fastened.
7. Reconnect the Battery: Reconnect the negative battery terminal.
8. Test: Test the new ignition lock cylinder with your key to ensure it functions correctly.
Important Considerations:
* Repair Manual: Obtain a detailed repair manual specific to your 1984 Jeep CJ7. This manual will provide step-by-step instructions with diagrams and torque specifications, significantly reducing the risk of damage.
* Special Tools: You may need specialized tools, such as a steering wheel puller, ignition lock cylinder removal tool, and possibly a socket set with metric and standard sizes.
* Key Matching: Ensure you have the correct key for the new ignition lock cylinder. Getting the wrong key will render the new cylinder useless. You may need to have the cylinder keyed to match your existing keys.
* Professional Help: If you're not comfortable performing this repair yourself, it's best to take your Jeep to a qualified mechanic. This is not a beginner's task, and improper installation can cause significant damage.
This process can be significantly more complex than described here, depending on your specific vehicle's configuration. Always consult a repair manual before attempting this repair. Failing to do so risks damage to your vehicle and potential injury.
