Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the strut assembly.

4. Disconnect the Strut

Remove the lower strut bolt using a socket set (may require a breaker bar for stubborn bolts).
Remove the top strut mounts by accessing them through the engine bay or trunk, depending on the strut's location.
Carefully detach the strut from the vehicle.

5. Replace the Strut

Install the new strut by reversing the removal process.
Ensure the top strut mount is torqued to the manufacturer's specifications (typically around 15-20 ft-lbs).
Reattach the lower strut bolt and torque it to the specified value (usually around 70-80 ft-lbs).

6. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and onto the ground.
Torque the lug nuts to the manufacturer's specifications (usually around 76-83 ft-lbs).

7. Final Checks

Reconnect the battery.
Inspect for any leaks or misalignments.
Test drive the vehicle to ensure proper handling.
