1. Preparation and Access:
* Steering Column Removal (Likely Necessary): You'll almost certainly need to remove the steering column, at least partially, to access the ignition switch. This involves removing the steering wheel (a significant undertaking itself, requiring a special steering wheel puller), and potentially other components like the turn signal switch and other column-mounted controls. Consult a repair manual specific to your 1968 Chevrolet pickup for detailed instructions on this.
* Identify the Switch: Once you have access to the steering column, locate the ignition switch itself. It's typically a cylindrical component behind the steering wheel.
2. Removal Procedure:
* Wiring Harness: Carefully disconnect the wiring harness from the ignition switch. Take photos or make detailed notes of the wire connections before disconnecting anything – this will be crucial for reassembly. Label each wire clearly.
* Retaining Clips/Screws: The ignition switch is usually held in place by one or more retaining clips or screws. These may be visible once the wiring harness is disconnected, or they may be hidden behind a bezel or cover. Carefully remove these fasteners.
* Switch Removal: Once the fasteners are removed, the ignition switch should slide out or be gently pulled free. There might be a slight resistance. Avoid using excessive force, as you could damage the switch or surrounding components.
3. Reassembly:
* Reverse the removal process carefully. Ensure all wires are properly connected according to your notes or photos.
* Test the ignition switch thoroughly before reassembling the steering column.
Important Considerations:
* Repair Manual: A factory service manual or a Haynes/Chilton manual specific to your 1968 Chevrolet pickup is absolutely essential. These manuals provide detailed diagrams, instructions, and torque specifications, which are crucial for successfully completing this repair. Improper reassembly can lead to damage and safety hazards.
* Special Tools: You'll likely need special tools, such as a steering wheel puller, various sockets, and possibly a small screwdriver set.
* Safety: Working on your vehicle's steering column and ignition system can be dangerous. Take your time, be meticulous, and prioritize safety. If you're not comfortable with this level of automotive repair, seek assistance from a qualified mechanic.
Disclaimer: This is a general guide. The specific steps may vary based on your truck's model and condition. Always consult a repair manual for detailed, vehicle-specific instructions. Attempting this repair without proper knowledge and tools could lead to damage to your vehicle or personal injury.
