Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the front or rear wheels (depending on which strut is being replaced) before lifting the vehicle.

2. Lift the Vehicle

Use a floor jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the struts.

3. Remove the Strut Assembly

Locate the top strut mount under the hood and remove the nuts using a socket wrench.
At the bottom of the strut, remove the bolts securing it to the steering knuckle using a socket and ratchet.
Carefully detach the strut from the vehicle, ensuring not to damage any surrounding components.

4. Replace the Strut

If using a new strut, compare it with the old one to ensure proper fitment.
Install the new strut into the strut tower and secure it with the nuts previously removed.
Attach the bottom of the strut to the steering knuckle using the bolts, torqueing them to the manufacturer's specifications (typically around 50-60 ft-lbs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value (usually around 80-90 ft-lbs).

6. Final Steps

Repeat the process on the opposite side if needed.
Ensure all tools are removed from the work area and perform a test drive to assess the handling and ride quality.
