1. Disconnect the Battery: This is crucial to prevent accidental airbag deployment (even though your 1984 model likely doesn't have one) and short circuits. Disconnect the negative (-) terminal first.
2. Remove the Steering Wheel: This usually requires a steering wheel puller. You can rent one from most auto parts stores. The puller applies even pressure to the steering wheel, preventing damage. There are usually three or more holes in the steering wheel rim which the puller engages.
* Important Note: Before using the puller, mark the steering wheel's position relative to the column. This helps with reinstallation and ensures the wheel is straight.
3. Access the Horn Contact (if applicable): Once the steering wheel is off, you'll see the horn contact. This is a metal piece with a couple of wires connected. Carefully disconnect these wires. They usually just push on or have a small retaining clip.
4. Removing the Hub (if applicable): If you're referring to the actual steering column hub (the part the steering wheel attaches to), it might require special tools depending on the design. Some might have a retaining nut or clip that needs to be removed. Others might simply slide off. If you're unsure, consult a repair manual specific to your 1984 El Camino. A visual inspection after removing the steering wheel will reveal how the hub is attached.
5. Reassembly: Reassemble in reverse order. Make sure to properly connect the horn wire(s) and tighten the steering wheel nut securely to the correct torque specification (consult a repair manual).
Important Considerations:
* Repair Manual: A Haynes or Chilton repair manual for your specific year and model of El Camino is highly recommended. These manuals provide detailed instructions with diagrams, making the process much safer and easier.
* Safety: Work in a well-lit area. Use appropriate tools to avoid damaging parts. If you're uncomfortable performing this task yourself, take your vehicle to a qualified mechanic.
If you can provide a picture of the "metal piece," I might be able to offer more specific instructions. Without a visual, it's difficult to say definitively what needs to be removed.
