Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Inspect the brake components while the wheel is off for any additional issues.

4. Remove the Ball Joint

Locate the ball joint and remove the cotter pin (if applicable) using pliers.
Use a socket set to remove the nut securing the ball joint to the control arm or steering knuckle.
Use a ball joint separator tool to detach the ball joint from the knuckle or control arm.

5. Install New Ball Joint

Position the new ball joint in place.
Secure it with the nut and torque to the manufacturer's specifications (typically around 30-50 lb-ft, but verify with a service manual).
Reinsert the cotter pin if applicable.

6. Reassemble

Reattach the wheel to the hub and tighten the lug nuts to the manufacturer’s recommended torque (usually around 80-100 lb-ft).
Remove jack stands and lower the vehicle.

7. Final Checks

Reconnect the battery.
Perform a final inspection of the suspension components for any loose parts.
