Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.
Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, impact wrench.

2. Remove the Wheel

Loosen the lug nuts on the front or rear wheel where the strut will be replaced.
Use a jack to lift the vehicle and securely place jack stands underneath.
Completely remove the lug nuts and take off the wheel.

3. Remove the Strut Assembly

Locate and remove the bolts securing the strut to the steering knuckle using the socket set.
Remove any retaining clips or bolts securing the strut to the upper strut mount in the engine bay or trunk.
Carefully detach the strut assembly from the vehicle, ensuring that all connections are free.

4. Compress the Strut Spring

Place the strut spring compressor around the spring of the strut assembly.
Gradually compress the spring until tension is relieved.
Remove the top strut nut using the impact wrench, and take off the strut mount and spring from the assembly.

5. Install New Strut Assembly

Place the new strut into position and reattach the upper strut mount, tightening the top nut to the manufacturer's torque specification.
Reattach the strut assembly to the steering knuckle and secure with the bolts, ensuring they are torqued to specification.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
Use the torque wrench to finish tightening the lug nuts to the specified torque.
