Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, screwdriver, pliers, gloves, safety goggles.
Raise the vehicle using a jack and secure it on jack stands.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the front or rear wheel (depending on which strut is being replaced).
2. Remove the wheel and set it aside.

3. Remove Strut Assembly

Sub-steps:
1. Remove the bolts securing the strut to the steering knuckle using a socket set.
2. Disconnect any brake line brackets attached to the strut.
3. Unbolt the strut from its top mount under the hood (may require removal of the engine cover).
4. Carefully remove the strut assembly from the vehicle.

4. Replace Strut

Sub-steps:
1. If reusing the spring, use a strut spring compressor to safely compress the spring and remove it from the old strut.
2. Install the spring onto the new strut, ensuring it is seated correctly and follows the manufacturer's specifications.
3. If using new struts, align the new strut in the same orientation as the old one.

5. Reinstall Strut Assembly

Sub-steps:
1. Position the new strut assembly back into the mounting location.
2. Secure the strut to the top mount and tighten the bolts to the manufacturer’s torque specifications.
3. Reattach the strut to the steering knuckle by tightening the bolts securely.
4. Reconnect any brake lines or sensors that were detached.

6. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle using the jack and remove the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications.
