Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted.
Safety warning: Ensure the vehicle is supported with jack stands before working underneath.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel from the hub to access the ball joint.

3. Disconnect Ball Joint

Use a socket set to remove the nut securing the ball joint to the control arm.
If necessary, use a ball joint separator tool to disconnect the ball joint from the steering knuckle.

4. Inspect and Replace Ball Joint

Remove the ball joint from its housing by pressing it out with a ball joint press.
Inspect the new ball joint for defects before installation.
Press the new ball joint into the housing following the manufacturer’s specifications.

5. Reattach Components

Reconnect the ball joint to the steering knuckle and secure it with the nut. Torque the nut to the manufacturer’s specification (usually around 40-50 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Check

Lower the vehicle back to the ground and then torque the lug nuts to the manufacturer’s specification (typically 80-100 ft-lbs).
Perform a final visual inspection to ensure everything is secure and in place.
