This is a general overview and specific steps may vary slightly depending on the year and model of your Cavalier. Always consult a repair manual specific to your vehicle's year and model. These manuals provide detailed instructions and torque specifications crucial for safety.
Tools you'll likely need:
* Jack and jack stands: Essential for safely lifting the vehicle. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Ball joint separator: A crucial tool for separating the ball joint from the control arm. Different types exist (pickle fork, ball joint press, etc.), and a press is generally preferred to avoid damage.
* Sockets and wrenches: Various sizes will be needed, likely including metric sizes.
* Hammer (if using a pickle fork): Use with caution to avoid damaging components.
* Torque wrench: Absolutely necessary to tighten bolts to the correct specifications.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized components.
* Grease: For the new ball joint.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Lift and Support: Safely lift the vehicle using the jack and securely place it on jack stands. Remove the wheel.
3. Disconnect Components: This will vary depending on the year and model. You'll likely need to disconnect the brake caliper, sway bar link, and possibly other suspension components to gain access to the ball joint. Take photos as you go to help with reassembly.
4. Separate Ball Joint: This is the most challenging part. Use a ball joint separator (preferably a press) to carefully separate the ball joint from the steering knuckle. A pickle fork can be used, but carries a higher risk of damaging the knuckle.
5. Remove the Old Ball Joint: Once separated, remove the old ball joint from the control arm. This often involves removing cotter pins, nuts, and possibly a retaining clip.
6. Install New Ball Joint: Carefully install the new ball joint into the control arm, ensuring it's properly seated.
7. Reassemble: Reinstall all the components you disconnected earlier, paying close attention to the order and torque specifications found in your repair manual.
8. Lower Vehicle: Carefully lower the vehicle from the jack stands.
9. Torque Specifications: Use a torque wrench to tighten all bolts to the manufacturer's specifications. This is crucial for safety and proper suspension function.
10. Test Drive: After reassembly, carefully test drive the vehicle to ensure everything is working correctly. Listen for any unusual noises or feel for any play in the steering.
Important Considerations:
* Pressing the Ball Joint: Using a ball joint press is highly recommended to avoid damage to the control arm or knuckle.
* Torque Specifications: Follow the torque specifications in your repair manual precisely. Over-tightening or under-tightening can lead to serious problems.
* Alignment: After replacing ball joints, it's essential to get a wheel alignment. This ensures proper tire wear and vehicle handling.
This is a simplified overview. Again, consult a repair manual specific to your vehicle for detailed instructions and torque specifications. If you're unsure about any step, it's best to seek professional help from a qualified mechanic. Improperly installed ball joints can be extremely dangerous.
