Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Always use wheel chocks and jack stands when lifting the vehicle.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated jacking points.
Secure the vehicle with jack stands to prevent any accidents.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel.
Keep the lug nuts in a safe place for reinstallation.

4. Remove Old Strut Assembly

Locate the strut assembly and remove any fasteners securing it to the steering knuckle and upper mount.
Disconnect any associated components (e.g., sway bar links, brake lines) carefully.
Remove the strut assembly from the vehicle.

5. Install New Strut Assembly

Position the new strut assembly in place and secure it using the previously removed fasteners.
Ensure all connections are tightened to the manufacturer’s specifications (consult the vehicle manual for torque values).

6. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Use a torque wrench to tighten the lug nuts to the recommended torque specifications.

7. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground using the hydraulic jack.

8. Final Check

Inspect the area around the struts for any clearance issues.
Ensure all components are secure and there are no leaks.
