Disconnect the battery to ensure safety while working on electronic components.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Inspect Control Arm Bushings:
- Check for cracks or excessive wear.
- If damaged, remove the control arm by unbolting it from the chassis and the ball joint.
- Replace the bushings with new ones, ensuring proper alignment.
Check Sway Bar Links:
- Remove the sway bar links if they show signs of wear.
- Install new sway bar links, tightening to manufacturer specifications (usually around 30 Nm).
Examine Shock Absorbers:
- Check for any leaks or physical damage.
- If necessary, unbolt the shock absorbers from the top and bottom mounts.
- Replace with new shock absorbers, ensuring to torque bolts to specifications (typically 45 Nm).

4. Reassemble and Lower Vehicle

Reattach all components securely, ensuring no loose parts are present.
Lower the vehicle back to the ground and torque all wheel bolts to specifications (usually 120 Nm).

5. Final Inspection
