Use wheel chocks to prevent the vehicle from rolling.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Remove the Old Ball Joints

Tools Required: Socket set, ball joint separator, torque wrench
Disconnect any components obstructing access to the ball joints (e.g., brake calipers, sway bar links).
Use a ball joint separator to disconnect the ball joint from the control arm.
Remove the bolts securing the ball joint to the steering knuckle.
Carefully extract the ball joint from the control arm.

4. Install the New Ball Joints

Parts Required: New ball joints
Insert the new ball joint into the control arm and secure it with the appropriate bolts.
Torque the bolts to the manufacturer’s specifications (typically around 45-65 ft-lbs, check the specific value for your model).
Reattach any components that were removed in the previous step.

5. Reassemble and Lower the Vehicle

Reinstall the front wheels and torque the lug nuts to the manufacturer’s specifications (generally around 100-110 ft-lbs).
Lower the vehicle from the jack stands and remove wheel chocks.
