Solution

1. Preparation

Gather tools and materials:
- Hydraulic jack
- Jack stands
- Pry bar
- Torque wrench
- Safety glasses
Ensure the vehicle is parked on a level surface and the emergency brake is engaged.

2. Lift the Vehicle

Use the hydraulic jack to lift the front of the vehicle.
Position jack stands under the vehicle's frame for safety and lower the jack.

3. Inspect Ball Joints

Visually check the ball joints for cracks or signs of wear.
Ensure there's no excessive grease leakage.

4. Perform Play Test

Vertical Play Test:
- Grasp the wheel at the 12 and 6 o'clock positions.
- Push and pull the wheel to check for play. Any noticeable movement indicates wear.
Horizontal Play Test:
- Grasp the wheel at the 3 and 9 o'clock positions.
- Push and pull to check for lateral movement. Any movement suggests the ball joint is worn.

5. Pry Bar Test

Insert the pry bar under the lower control arm.
Apply upward pressure and observe the ball joint. Movement indicates significant wear.

6. Reassemble and Lower Vehicle

If the ball joints are in good condition, reassemble any components removed.
Carefully remove the jack stands and lower the vehicle.
