Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels with a lug wrench.

2. Remove the Old Ball Joints

Disconnect Components: Remove any components obstructing access to the ball joints (e.g., brake caliper, rotor, and suspension components).
Remove Retaining Nut: Unscrew the nut that secures the ball joint to the control arm using the socket set.
Separate Ball Joint: Use a ball joint separator tool or a pry bar to detach the ball joint from the steering knuckle.

3. Inspect and Replace

Inspect Control Arm: Examine the control arm for damage or wear; replace if necessary.
Install New Ball Joint: Position the new ball joint into the control arm and secure it with the retaining nut, tightening to the manufacturer's specified torque.
Reattach Components: Reinstall any components that were removed for access, ensuring all nuts and bolts are properly tightened.

4. Reassemble and Lower Vehicle

Reinstall Wheels: Place the wheels back on the vehicle and hand-tighten the lug nuts.
Lower the Vehicle: Carefully lower the vehicle from the jack stands and remove the jack.
Torque Lug Nuts: Once the vehicle is on the ground, torque the lug nuts to the specified value.
