Here's a general outline. Specific details might vary slightly depending on the exact trim level and any modifications to your car. Always consult a repair manual specific to your 1969 Chevy Nova for detailed instructions and diagrams. A factory service manual is the best resource.
1. Preparation:
* Disconnect the Battery: This is crucial.
* Gather Tools: You'll need various sockets, wrenches (metric and possibly standard), screwdrivers (Phillips and flathead), possibly a puller, and potentially a steering wheel puller.
* Protect Yourself: Wear safety glasses and gloves.
2. Steering Wheel Removal:
* Remove the horn cap and nut: This will usually expose the steering wheel retaining bolt(s).
* Remove the steering wheel: Use a steering wheel puller if necessary. This is often a three-armed tool that clamps around the wheel and pulls it off the shaft. Be aware that the steering wheel may be very tight.
3. Column Components Removal:
* Disconnect the Steering Column Shaft: This connects to the steering gear box. There will likely be a clamp or bolt securing it. You may need to carefully remove or loosen parts of the linkage to allow for easier access.
* Disconnect the Ignition Switch: Locate the wiring harness connected to the ignition switch on the steering column. Carefully disconnect the wiring harness. Diagram your connections before disconnecting anything.
* Disconnect the Turn Signal Switch and Wiper Switch: Locate and disconnect the wiring harnesses for these switches. Again, diagram the connections.
* Remove the Column Shifter (if applicable): Disconnect any linkage associated with the column-mounted shifter.
* Remove the Steering Column Mounting Bolts: There will be bolts (usually at the bottom of the column) and possibly additional fasteners securing the column to the firewall or dashboard. These will need to be removed.
* Carefully Remove the Column: Once all the fasteners and connections are loose, carefully lower and remove the steering column from the vehicle. It might be helpful to have a helper to support the column's weight.
4. Reassembly:
Reassembly is the reverse of removal. Ensure all connections are secure and properly aligned. Pay close attention to the wiring connections.
Important Considerations:
* Column Shaft Alignment: Take note of the alignment of the steering shaft before disconnecting it. This is crucial for proper reassembly.
* Wiring Diagrams: Having access to a wiring diagram is essential to ensure that all the electrical connections are correctly reconnected.
* Repair Manual: A shop manual is invaluable. It provides detailed steps and illustrations.
This is a complex process. If you're not comfortable with automotive repair, it's best to consult a professional mechanic. Improper removal or reinstallation can lead to damage to your vehicle or safety issues.
