2. Lift the Vehicle

Use a hydraulic jack to raise the vehicle and secure it with jack stands.
Remove the wheels to access the suspension components.

3. Inspect and Replace Components

Ball Joints and Bushings
- Inspect the condition of the ball joints and bushings.
- If damaged, remove the bolts securing the ball joints and bushings using a socket set.
- Replace with new parts, applying the manufacturer's recommended torque specifications.
Strut Assembly
- Check the strut mounts for wear. If necessary, remove the strut assembly by unbolting it from the knuckle and strut tower.
- Inspect for oil leaks; if present, replace the struts.
- Reinstall the new struts, ensuring proper alignment and torque specifications.

4. Reassemble

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.
