Secure the vehicle on jack stands.
Remove the lug nuts completely and take off the front wheels.

3. Disassemble Strut Assembly

Locate the strut assembly at the front suspension.
Remove the bolts securing the strut to the steering knuckle using a socket set.
Disconnect any brake lines or ABS sensors attached to the strut.
Remove the nuts securing the strut to the upper mount using a socket set.
Carefully remove the strut assembly from the vehicle.

4. Replace Strut

Remove the top nut on the strut mount to take off the strut from the spring.
Replace the old strut with the new one, ensuring proper alignment with the mount.
Reattach the coil spring to the new strut, ensuring it is seated correctly.
Remove the spring compressor carefully once the strut and spring are secured.

5. Reinstall Strut Assembly

Position the strut assembly back into the vehicle and secure it with the upper mount nuts.
Reattach the lower portion of the strut to the steering knuckle using the previously removed bolts.
Reconnect any brake lines or ABS sensors that were disconnected.

6. Reinstall Wheels

Place the wheels back onto the wheel hubs.
Hand-tighten the lug nuts.
