Here's a general overview. Always consult a detailed repair manual specific to your 1967 Impala for precise instructions and torque specifications. This is a summary and omits crucial safety details.
Tools You'll Need (at minimum):
* Spring Compressor: This is absolutely essential and probably the most critical tool. A quality, correctly sized compressor is needed to safely compress the springs. Improper use can cause serious injury.
* Jack and Jack Stands: Securely support the vehicle. Never work under a vehicle supported only by a jack.
* Wheel Chocks: To prevent the car from rolling.
* Sockets and Wrenches: Various sizes to remove and install components.
* Impact Wrench (Highly Recommended): Makes the job significantly easier.
* Penetrating Oil: To loosen rusted bolts.
* Torque Wrench: For proper tightening of bolts.
* Gloves and Safety Glasses: Protect yourself.
* Shop Manual: A 1967 Impala specific shop manual is invaluable.
General Steps (Highly Simplified):
1. Safety First: Chock the rear wheels, securely jack up the front of the car, and place it on jack stands. Disconnect the negative battery terminal.
2. Remove the Wheel and Tire: Remove the wheel and tire from the side you're working on.
3. Remove the Brake Caliper: Carefully remove and support the brake caliper to keep the brake lines from being strained or damaged.
4. Remove the Control Arm: Depending on your specific setup, you might need to disconnect and remove the lower control arm. This may involve removing ball joints (use a ball joint separator tool). This step is crucial for enough space to work with the springs.
5. Compress the Spring: This is where the spring compressor is vital. Carefully and evenly compress the coil spring using the compressor. Ensure the compressor is securely attached and the spring is compressed enough to allow for removal of the upper control arm mount and the spring itself.
6. Remove the Old Spring: Once the spring is compressed enough, remove the upper control arm mount bolt(s), then remove the spring.
7. Install the New Spring: Install the new spring in the reverse order of removal. Make sure it's seated correctly in all the mounts.
8. Release the Spring Compressor: Slowly and carefully release the spring compressor. Ensure everything remains in place.
9. Reinstall Components: Reinstall the upper control arm mount, the control arm (if removed), the brake caliper, the wheel and tire.
10. Lower the Vehicle: Carefully lower the vehicle and check all your work.
Important Considerations:
* Spring Height: New springs may settle over time. Measure the height of the old springs and compare it to the new ones.
* Alignment: After installing new springs, you'll almost certainly need a wheel alignment.
Disclaimer: This is a simplified overview. Incorrectly installing springs can be dangerous. Consult a detailed shop manual and consider seeking professional help if you lack the necessary experience and tools. Improper installation can cause serious injury or damage to your vehicle.
