Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Safety warning: Disconnect the battery before working on electrical components.

2. Lift the Vehicle

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

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Safety warning: Ensure the vehicle is securely supported on jack stands before removing the wheel.

4. Remove the Strut Assembly

Disconnect any electrical connections, if applicable, from the strut.
Remove the bolts securing the strut to the steering knuckle using a socket set.
Unbolt the upper strut mount in the engine compartment using the appropriate socket.
Carefully remove the strut assembly from the vehicle.

5. Install New Struts

Position the new strut assembly into place, ensuring proper alignment with the upper and lower mounting points.
Tighten the upper strut mount bolts to manufacturer specifications (typically around 35-45 ft-lbs).
Reattach the strut to the steering knuckle and secure with the bolts (typically around 70-85 ft-lbs).

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (usually 100-130 ft-lbs).

7. Final Checks

Reconnect the battery if it was disconnected.
Ensure all tools are removed from the engine bay and under the vehicle.
