1. Preparation

Gather Tools and Parts: Ensure you have a socket set, jack stands, and replacement struts.
Safety Precautions: Park the vehicle on a level surface, engage the parking brake, and wear safety glasses.

2. Lift the Vehicle

Steps:
1. Use a jack to lift the front or rear of the vehicle as needed.
2. Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheels

Steps:
1. Use a lug wrench to loosen the lug nuts on the wheel(s) above the struts being replaced.
2. Remove the lug nuts and take off the wheel.

4. Remove the Old Struts

Steps:
1. Locate the bolts securing the strut to the steering knuckle and the strut tower.
2. Use a socket wrench to remove the bolts from the strut tower and the steering knuckle.
3. Carefully detach the strut from the vehicle and remove it.

5. Install the New Struts

Steps:
1. Position the new strut in place of the old one.
2. Secure the strut to the steering knuckle and strut tower using the bolts.
3. Torque the strut tower bolts to the manufacturer’s specifications (typically around 35-45 ft-lbs).

6. Reassemble the Vehicle

Steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Once on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specification (typically around 76 ft-lbs).
