Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical suspension components.

2. Raise the Vehicle

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

3. Inspect and Replace Components

Struts/Shocks:
- Remove the wheel to access the strut/shock assembly.
- Inspect for leaks or damage; replace if necessary.
- Follow manufacturer specifications for installation torque values.
Bushings:
- Check suspension bushings for cracks or wear.
- Use a bushing removal tool to replace worn bushings, ensuring proper alignment during installation.
Ball Joints:
- Inspect ball joints for excessive play or wear.
- Replace if needed by removing the retaining nut and using a ball joint separator to disengage.
Mounts:
- Check for any damaged strut or shock mounts.
- Replace by unbolting the old mount and installing the new one, ensuring correct orientation.

4. Reassemble and Lower Vehicle

Reinstall the wheel and torque the lug nuts to manufacturer specifications.
Remove the jack stands and lower the vehicle back to the ground.

5. Final Checks

Reconnect the battery if it was disconnected.
Perform a final visual inspection of all components to ensure proper installation.
