Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel to access the strut assembly.

3. Remove Strut Assembly

Locate the upper strut mount under the hood and remove the bolts securing the strut to the mount using a socket set.
Remove any additional components that may obstruct the strut removal (e.g., brake line brackets).
Use a spring compressor to safely compress the spring on the strut, following the manufacturer's instructions.
Remove the lower strut bolt using a socket or wrench to detach the strut from the steering knuckle.
Carefully extract the strut assembly from the vehicle.

4. Install New Strut

Replace the old strut with the new one by reversing the removal process.
Ensure the new strut is properly aligned with the steering knuckle and secure it with the lower strut bolt.
Reattach the upper strut mount and tighten the bolts to the manufacturer's torque specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and then torque the lug nuts to the specified value.
Remove the jack stands and lower the car completely.
Test drive the vehicle to verify improved ride quality and handling.
