Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Strut spring compressor
Pry bar
Pliers

2. Remove the Wheel

Use a socket wrench to loosen the lug nuts on the wheel corresponding to the strut being replaced.
Remove the wheel and set it aside.

3. Remove the Strut Assembly

Disconnect the sway bar link from the strut using a socket.
Remove the lower strut bolt using a socket and wrench; use a pry bar if necessary to separate the strut from the control arm.
Open the hood and remove the strut mounting nuts from the top of the strut tower using a socket.
Carefully lift the strut assembly out of the vehicle.

4. Replace the Strut

Use a strut spring compressor to compress the coil spring on the old strut.
Remove the top strut mount and spring from the old strut.
Install the spring and mount onto the new strut, ensuring proper alignment.
Slowly decompress the spring and ensure the strut is properly seated.

5. Reinstall the Strut Assembly

Position the new strut assembly in the strut tower and secure it with the upper mounting nuts.
Reconnect the lower strut bolt to the control arm and tighten to manufacturer specifications.
Reattach the sway bar link to the strut.

6. Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque.
