Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, ball joint separator tool, and safety gloves.
Safely lift the vehicle and secure it on jack stands to ensure stability.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts while the vehicle is on the ground.
2. Lift the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel to access the suspension components.

3. Inspect and Test Ball Joint

Sub-steps:
1. Visually inspect the ball joint for any signs of damage or wear.
2. Using your hand, try to move the ball joint by grasping the lower control arm and pushing it upward. If there's excessive movement, the ball joint may need replacement.
3. If necessary, use a ball joint separator tool to remove the ball joint for further inspection.

4. Replace Ball Joint (if wear is found)

Sub-steps:
1. Remove the retaining nut from the ball joint using the appropriate socket.
2. Use the ball joint separator to disconnect the ball joint from the control arm.
3. Install the new ball joint by reversing the removal steps, ensuring it's seated correctly.
4. Torque the retaining nut to the manufacturer’s specifications (typically around 30-40 Nm).
5. Reattach the wheel and torque the lug nuts to the specified value (usually 120 Nm).
