Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather tools and safety equipment.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, ball joint separator tool.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands under the frame.
Remove the front wheels using the lug wrench.

3. Remove the Ball Joint

Use the socket set to remove the nuts and bolts securing the ball joint to the control arm and steering knuckle.
If necessary, use a ball joint separator tool to detach the ball joint from the steering knuckle.

4. Inspect and Replace

Inspect the old ball joint for wear and compare it with the new one.
If replacement is needed, install the new ball joint by reversing the removal steps.
Ensure that all nuts and bolts are torqued to the manufacturer's specifications (refer to service manual for specific torque values).

5. Reassemble

Reattach the wheel and lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque.
