Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, impact wrench (optional).
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands to ensure safety during the repair.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Remove the Strut Assembly

Disconnect the sway bar link: Use a socket to remove the bolt securing the sway bar link to the strut.
Remove the lower strut mount bolts: Using a socket, remove the bolts securing the strut to the lower control arm.
Remove the upper strut mount nuts: Open the hood and locate the strut tower. Remove the nuts securing the strut mount using a socket.
Take out the strut assembly: Carefully pull the strut assembly out from the wheel well.

5. Replace the Strut

Compress the spring: Use a strut spring compressor to safely compress the coil spring on the old strut.
Remove the old strut from the spring: Remove the top strut mount and bearing using a socket and take out the old strut.
Install the new strut: Position the new strut in place and install the upper strut mount and bearing.
Release the spring compressor: Carefully release the tension on the spring compressor.

6. Reinstall the Strut Assembly

Insert the strut assembly back into the vehicle: Position the strut in the strut tower and secure it with the upper nuts.
Reattach lower strut mount: Attach the strut to the lower control arm by tightening the lower mount bolts to the manufacturer's torque specifications.
Reconnect the sway bar link: Reattach the sway bar link to the strut and tighten it.

7. Reinstall the Wheel

Put the wheel back on and hand-tighten the lug nuts.

8. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque.
