Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery as a safety measure.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle with jack stands under the frame.
Remove the front wheels using a socket set.

3. Inspect Ball Joints

Visually check the ball joint for any signs of wear, such as cracks in the rubber boot.
Using your hands, try to move the ball joint; any significant play indicates wear.

4. Check for Movement

Using a pry bar, place it under the wheel hub and lift slightly. Observe the ball joint for any gap or movement.
If there is visible movement, the ball joint should be replaced.

5. Replacement (if necessary)

If wear is detected, remove the cotter pin and nut securing the ball joint.
Use a ball joint separator tool to detach the ball joint from the control arm.
Install the new ball joint, securing it with the nut and cotter pin. Torque to manufacturer's specifications (typically around 60-80 ft-lbs).
Reinstall the wheel and lower the vehicle.
