Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Wheels

Use a socket set to remove the lug nuts from the front wheels.
Carefully take off the wheels and set them aside.

4. Inspect Struts

Visually inspect the strut for leaks, dents, or other damage.
Check for any rust or corrosion on the strut housing.

5. Remove the Struts

Disconnect the sway bar link using a wrench.
Remove the bolts securing the strut to the steering knuckle.
Access the strut top mount in the engine bay or under the dash and remove the retaining nuts.
Carefully pull the strut out from the vehicle.

6. Replace with New Struts

Install new struts in the reverse order of removal.
Ensure that all bolts are torqued to the manufacturer's specifications (refer to service manual).
Reattach the sway bar link.

7. Reinstall the Wheels

Place the wheels back on the vehicle and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.

8. Final Inspection

Check the alignment of the wheels after the strut replacement.
Ensure that all components are securely fastened.
