Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery to prevent any electrical issues.

Tools Required:

Socket set
Torque wrench
Jack and jack stands
Strut spring compressor
OBD-II scanner (for diagnostic purposes)

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which struts are being replaced.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

Disconnect any electrical connectors related to the struts if applicable.
Unbolt the strut from the lower control arm using the socket set.
Remove the bolts securing the strut to the upper mount in the engine bay or trunk.
Carefully extract the strut assembly from the vehicle.

5. Replace the Strut

Use a strut spring compressor to safely compress the spring on the old strut.
Remove the top mount and spring from the old strut and install them on the new strut.
Reassemble the strut assembly, ensuring all components are securely fastened according to manufacturer specifications.

6. Reinstall the Strut Assembly

Position the new strut assembly in place and secure it to the upper mount and lower control arm.
Torque all bolts to the manufacturer's specified values.

7. Reattach the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value once it is on the ground.

8. Final Checks

Reconnect the battery.
Start the vehicle and check for any warning lights related to the suspension system.
