Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, strut spring compressor, and pry bar.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Securely place jack stands under the vehicle’s frame for safety.
Remove the front wheels using a lug wrench.

3. Remove the Strut Assembly

Locate the strut assembly and remove the lower mounting bolts using a socket set.
Disconnect the brake line and any sensors attached to the strut.
Remove the top strut mounting nuts located under the hood using the appropriate socket.
Carefully pull the strut assembly out of the wheel well.

4. Replace Strut

Use a strut spring compressor to safely compress the coil spring on the old strut.
Once compressed, remove the strut top nut and carefully release the spring.
Install the coil spring onto the new strut, securing it with the top nut. Ensure it is torqued to manufacturer specifications.
Reinstall the strut assembly into the vehicle, following the reverse order of removal.

5. Reassemble and Lower the Vehicle

Reattach the top strut mounting nuts and torque them to specification.
Reconnect the brake line and any sensors.
Reinstall the lower mounting bolts and torque them to specification.
Replace the wheels and lower the vehicle to the ground.

6. Final Inspection

Reconnect the battery and check for any unusual noises during a test drive.
Inspect for leaks around the new strut assembly.
