Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported on jack stands before starting any work.

2. Remove the Wheel

Loosen the lug nuts on the wheel where the strut is being replaced.
Raise the vehicle using a jack and securely place jack stands under the vehicle.
Remove the lug nuts and take off the wheel.

3. Remove the Strut Assembly

Locate the strut assembly and remove any plastic covers if present.
Disconnect the brake line and ABS sensor wire from the strut (if applicable).
Unbolt the strut from the steering knuckle using a socket set.
Unbolt the strut from the strut tower in the engine compartment (typically located under the hood).
Carefully remove the strut assembly from the vehicle.

4. Replace the Strut

Use a strut spring compressor to safely compress the spring on the old strut.
Remove the top nut of the strut to release the spring and separate it from the strut.
Install the spring onto the new strut, ensuring proper alignment.
Reinstall the top nut and torque to the manufacturer's specifications.

5. Reinstall the Strut Assembly

Position the new strut assembly back into the vehicle.
Bolt the strut to the strut tower and torque it to the recommended specifications.
Reattach the strut to the steering knuckle and torque the bolts accordingly.
Reconnect the brake line and ABS sensor wire.

6. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications.
