Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels depending on the area of concern.

3. Inspect and Replace Components

Inspect Struts and Shock Absorbers:
- Check for signs of leaks or damage.
- If damaged, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts and reassemble.
Inspect Bushings and Mounts:
- Check for wear or deterioration in control arm bushings and sway bar links.
- Remove any worn bushings and replace with new ones using a press or appropriate tool.
Check Air Suspension (if applicable):
- Inspect air lines for leaks.
- Test the air suspension compressor and replace it if it fails to operate correctly.

4. Reassemble and Torque

Reattach the strut assembly or control arms.
Ensure all bolts are torqued to manufacturer specifications (refer to service manual for torque values).
Reinstall the wheels and lower the vehicle.

5. Final Checks

Reconnect the battery and clear any error codes with the OBD-II scanner.
Check the air suspension system for proper height adjustments.
