Solution

1. Preparation

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

2. Lift the Vehicle

Use the jack to lift the front of the vehicle.
Place jack stands under the vehicle's frame for safety and lower the vehicle onto them.

3. Remove the Wheel

Using a socket set, remove the lug nuts from the front wheel.
Take off the wheel and set it aside.

4. Inspect and Test Ball Joints

Visual Inspection: Check the ball joint boot for tears or damage. Ensure that there is no grease leaking out.
Movement Test: Using your hands, try to move the ball joint in various directions. If you notice excessive play, it may need replacement.
Ball Joint Separator Tool: Insert the tool between the ball joint and control arm, and gently pry it apart to feel for any abnormal movement.

5. Replace Ball Joint (if necessary)

If the ball joint is worn, remove the retaining nut using the socket set.
Use the ball joint separator to detach it from the control arm.
Install the new ball joint by reversing these steps, ensuring proper torque specifications are followed (typically around 30-50 ft-lbs, but check manufacturer specifications).
Reinstall the wheel and lug nuts, tightening them to the manufacturer’s specifications.
