Solution

1. Preparation

Tools Required: Hydraulic lift or jack stands, wheel chocks, lug wrench, pry bar, torque wrench, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Lift the Vehicle

Use a hydraulic lift or jack to raise the front of the vehicle.
Secure the vehicle with jack stands to prevent any movement while working.

3. Remove Front Wheels

Use a lug wrench to loosen and remove the lug nuts on both front wheels.
Carefully remove the wheels and set them aside.

4. Inspect Ball Joints

Locate the ball joints on the lower and upper control arms.
Visually inspect for any visible cracks, tears, or excessive grease leakage.
Grasp the ball joint with your hand and check for any play by moving it up and down or side to side.

5. Use Pry Bar for Play Testing

Insert a pry bar under the wheel hub or control arm and apply upward pressure.
Observe if there is any movement in the ball joint, which indicates wear.

6. Reassemble and Lower the Vehicle

If ball joints are in good condition, reattach the wheels and torque the lug nuts to the manufacturer's specifications (usually around 100-120 Nm).
If ball joints need replacement, follow manufacturer-specific procedures for removal and installation.
Lower the vehicle safely back to the ground.
