However, if you're determined to do it yourself, here's a general overview. This is NOT a comprehensive guide, and specific procedures may vary slightly depending on the exact model and condition of your Nova. Always consult a repair manual specific to your 1970 Chevy Nova for detailed instructions, torque specifications, and safety precautions.
Tools You'll Likely Need:
* Ball Joint Separator: Essential for removing the ball joint from the control arm. Several types exist (pickle forks, hydraulic separators, etc.), and a hydraulic separator is generally preferred to avoid damaging the control arm.
* Socket Set and Wrenches: Various sizes, including metric and SAE, depending on your Nova's specific fasteners.
* Jack and Jack Stands: Crucial for safely supporting the vehicle. Never work under a vehicle supported only by a jack.
* Wheel Chocks: To prevent the vehicle from rolling.
* Torque Wrench: Absolutely necessary to tighten the bolts to the correct specification. Incorrect torque can lead to premature failure or damage.
* Hammer and Punch: May be needed to help loosen stubborn parts.
* Penetrating Oil: Soak all bolts and joints before attempting to remove them.
* Grease Gun: To pack the new ball joints with grease.
* Pry Bar: May be helpful in separating components.
* Safety Glasses and Gloves: Always wear appropriate safety gear.
General Steps (Again, consult your repair manual for precise details):
1. Safety First: Securely jack up the vehicle and place it on jack stands. Engage the parking brake and use wheel chocks.
2. Disconnect Components: Disconnect the sway bar link, brake caliper (and potentially the brake line), and cotter pin and castle nut from the ball joint.
3. Remove the old ball joint: This is where the ball joint separator comes in. Carefully separate the ball joint from the control arm. This is the most challenging part of the job and requires patience and the right tools to avoid damage.
4. Install the new ball joint: Carefully install the new ball joint into the control arm. Some new ball joints may require pressing in, while others may use a threaded design. Again, your repair manual will provide specifics.
5. Reassemble: Reinstall all disconnected components, ensuring everything is properly aligned. Pay close attention to the correct orientation of parts.
6. Torque Specifications: Use your torque wrench to tighten all fasteners to the manufacturer's specified torque.
7. Lower the vehicle: Carefully lower the vehicle to the ground.
8. Test: After installation, carefully test the steering and suspension for proper function. A test drive may be necessary, but do so cautiously.
Important Considerations:
* Pressing: Some ball joint replacements require a press to install the new joint correctly.
* Alignment: After replacing ball joints, you will almost certainly need a wheel alignment. This is crucial for safe and proper vehicle handling.
* Parts: Ensure you purchase the correct ball joints for your specific 1970 Chevy Nova model. Using incorrect parts can lead to serious issues.
This is a simplified overview. You absolutely need a detailed repair manual specific to your 1970 Chevy Nova. Improperly replacing ball joints can result in serious accidents. If you are not confident in your abilities, take your car to a qualified mechanic. The cost of repair will be far less than the potential cost of an accident caused by improperly installed ball joints.
