This is a general overview; consult a repair manual specific to your 1974 Nova for detailed instructions, torque specifications, and wiring diagrams. The steps below may vary slightly depending on your specific model and options.
1. Preparation:
* Gather Tools: You'll need a variety of tools, including sockets (various sizes), wrenches, screwdrivers (Phillips and flathead), pliers, a steering wheel puller, possibly a pickle fork (use with caution!), and potentially a torque wrench.
* Disconnect Battery: Disconnect the negative (-) terminal of your car battery.
* Safety First: Wear safety glasses and gloves.
2. Removing the Old Steering Column:
* Steering Wheel: Remove the steering wheel using a steering wheel puller. This is often the most challenging part. You'll need to find the correct size puller for your steering wheel. There are usually holes or slots behind the wheel to attach the puller.
* Column Shifter (if applicable): If you have a column-mounted shifter, disconnect the linkage.
* Wiring Harness: Disconnect the wiring harness from the steering column. Carefully label each wire before disconnecting to ensure proper reconnection. Take pictures!
* Column Mounting Bolts: Locate and remove the bolts that secure the steering column to the firewall and/or the steering column support bracket. The number and location of these bolts will vary.
* Steering Shaft: Disconnect the steering shaft from the gear box. This usually involves unbolting a coupling or clamp. This can be tricky and may require special tools.
* Lower Column Support: Remove the lower column support, if present.
* Remove the Column: Carefully remove the steering column from the vehicle.
3. Installing the New Steering Column:
* Installation is essentially the reverse of removal: Carefully align the new steering column with the steering shaft and gearbox.
* Secure the Column: Tighten the bolts that secure the steering column to the firewall and/or support bracket, ensuring the column is properly aligned. Use the correct torque specifications from your repair manual.
* Reconnect Steering Shaft: Carefully connect the steering shaft to the gearbox, ensuring it's properly seated.
* Reconnect Wiring: Reconnect the wiring harness, making sure each wire is connected to the correct location. Refer to your labels or pictures.
* Reconnect Column Shifter (if applicable): If applicable, reconnect the column shifter linkage.
* Install Steering Wheel: Install the new or refurbished steering wheel. Make sure it's tight!
* Test: Reconnect the battery and test the steering, horn, and turn signals (as well as the shifter if applicable) to ensure everything works correctly.
Important Considerations:
* Column Alignment: Proper alignment is crucial for safe operation. A misaligned column can lead to difficult steering and potential safety hazards.
* Repair Manual: A factory service manual specific to your 1974 Nova is highly recommended. This will provide detailed instructions, diagrams, and torque specifications.
* Professional Help: If you are not comfortable performing this repair yourself, it is strongly recommended to take your vehicle to a qualified mechanic. Incorrect installation can lead to serious safety issues.
This is a complex procedure, and this is only a broad overview. Always prioritize safety and consult a repair manual before attempting this repair. Improper installation can lead to serious injury or damage.
