Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, pry bar, torque wrench, socket set, and safety glasses.
Safety Warning: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels but do not remove them entirely.
Position the jack under the vehicle's designated lift points and raise it until the wheels are off the ground.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Fully remove the loosened lug nuts and take off the wheel.
Set the wheel aside in a safe place.

4. Inspect the Ball Joint

Use the pry bar to lift the lower control arm gently.
Observe the ball joint for any movement or separation from the control arm.
If movement is detected, the ball joint may need replacement.

5. Replace the Ball Joint (if necessary)

Remove the cotter pin and nut securing the ball joint to the steering knuckle.
Use a ball joint separator tool to disconnect the ball joint from the knuckle.
Remove the ball joint from the control arm by unscrewing it from its mounting.
Install the new ball joint by reversing the removal steps, ensuring it is firmly seated and secured.
Torque the ball joint nut to the manufacturer's specified torque value (usually around 40-60 ft-lbs, but check specific service manual).

6. Reassemble and Lower the Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).
