Here's a general overview of the process. This is not a complete guide, and you should consult a detailed shop manual specific to your 1972 Corvette before attempting this repair. A Haynes or Chilton manual, or a factory service manual, are excellent resources.
1. Preparation and Disassembly:
* Disconnect the battery: This is crucial to prevent accidental short circuits.
* Remove the steering wheel: This usually involves using a steering wheel puller. Note the position of the wheel relative to the column before removing it.
* Remove the column shroud and other trim pieces: Carefully remove all components surrounding the steering column to gain access to its internal workings. Take pictures as you go to help with reassembly.
* Disconnect all electrical connections: This includes the horn, turn signals, and other components connected to the column. Again, take photos or make detailed notes.
* Disconnect the steering linkage: Separate the steering column from the steering gear box.
* Carefully disassemble the column: This involves removing various components like the tilt mechanism, the telescopic tube, the ignition switch, and the various shafts and gears. Pay close attention to the order of parts and their orientation. Use penetrating oil to help loosen any seized components.
2. Inspection and Part Replacement:
* Thoroughly inspect all parts: Look for wear, damage, broken parts, or excessive play.
* Replace worn or damaged parts: This is crucial for safety. Common problem areas include the tilt mechanism, the telescopic sleeve, bushings, and the ignition switch. Source replacement parts from reputable suppliers specializing in classic Corvette parts. Using inferior parts can compromise the steering column's integrity.
3. Reassembly:
* Reassemble the column in reverse order of disassembly: Refer to your service manual for precise instructions and diagrams. Pay close attention to the proper alignment of gears, shafts, and other components.
* Lubricate all moving parts: Use appropriate grease and lubrication to ensure smooth operation.
* Reconnect all electrical connections: Ensure all connections are secure and properly grounded.
* Reconnect the steering linkage: Make sure the linkage is properly aligned.
* Reinstall the steering wheel: Ensure it's properly tightened and aligned.
* Reinstall the column shroud and trim pieces: Ensure everything is correctly fitted.
4. Testing and Adjustment:
* Test the tilt and telescopic functions: Make sure the column tilts and telescopes smoothly and securely.
* Check for proper steering alignment: Have the steering alignment checked by a professional.
* Test all electrical functions: Ensure the horn, turn signals, and other functions are working correctly.
Important Considerations:
* Specialized Tools: You'll likely need specialized tools such as a steering wheel puller, various sockets and wrenches, and possibly a column alignment tool.
* Safety: This is a complex repair with potential safety implications. If you're not comfortable performing this repair yourself, consider taking it to a qualified mechanic specializing in classic Corvettes. A poorly repaired steering column can be extremely dangerous.
* Service Manual: Obtain a detailed service manual for your 1972 Corvette. This is essential for successful completion of the repair.
This is a simplified overview. The actual process is far more involved and requires careful attention to detail. Again, do not attempt this repair without a detailed service manual and the necessary mechanical expertise. If you are not experienced with this type of work, it's strongly advised to seek professional help.
