Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands to prevent it from falling.

3. Remove Wheel

Using a lug wrench, remove the lug nuts from the front wheel.
Take off the wheel to access the ball joints.

4. Inspect and Replace Ball Joints

Remove the Ball Joint:
- If the ball joint is worn, remove the castle nut using a socket set.
- Use a ball joint separator to disconnect the ball joint from the control arm.
Install New Ball Joint:
- Position the new ball joint in place.
- Reattach the castle nut and torque it to the manufacturer's specifications (typically around 37-52 ft-lbs depending on the model).
- Ensure that the cotter pin is installed if applicable.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specification (usually around 75-90 ft-lbs).
Reconnect the battery.
