- Penetrating lubricant (e.g., WD-40)
2. Safety First:
- Make sure to engage the parking brake and chock the wheels opposite the side you're working on.
3. Raise the Vehicle:
- Position the jack under a designated lifting point on the Altima and raise it until the affected wheel is off the ground.
- Secure the vehicle using jack stands.
4. Locate Lower Ball Joint:
- The lower ball joint is situated on the lower control arm, where the control arm connects to the steering knuckle.
5. Remove Wheel and Caliper:
- Take off the lug nuts and remove the wheel.
- Locate and remove the bolts holding the brake caliper in place.
- Suspend the caliper using zip ties or wire to prevent it from hanging on the brake hose.
6. Disconnect Control Arm Stabilizer:
- Identify the control arm stabilizer, a metal link connecting the control arm to the frame.
- Remove the bolts securing the stabilizer to the control arm.
7. Break Loose Ball Joint Nut:
- Spray penetrating lubricant around the ball joint nut.
- Using the socket wrench, loosen the nut that holds the ball joint to the steering knuckle.
8. Pry the Ball Joint Free:
- Use a pry bar to pry the ball joint free of the steering knuckle.
- Be careful not to damage the CV boot.
9. Remove the Old Ball Joint:
- Once the ball joint is separated from the knuckle, remove the nuts and bolts securing it to the control arm.
- Take out the old ball joint.
10. Install the New Ball Joint:
- Align the new ball joint with the corresponding holes on the control arm.
- Insert the bolts and nuts and tighten them securely.
11. Reconnect Control Arm Stabilizer:
- Reinstall the control arm stabilizer by attaching it to the control arm.
12. Retighten Ball Joint Nut:
- Tighten the ball joint nut to the specified torque as mentioned in your vehicle's service manual.
13. Reattach Caliper and Wheel:
- Reattach the brake caliper and the wheel.
14. Lower the Vehicle:
- Lower the vehicle using the jack until it is safely back on the ground.
15. Test Drive and Alignment:
- After the repair, take your Altima for a test drive to check if the steering feels smooth and consistent.
- Consider getting a wheel alignment done to ensure proper tire wear and handling.
Remember, automotive repairs like this can be complex and potentially hazardous. If you're unsure about any steps, it's best to seek professional assistance from a qualified mechanic.
