Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, wrench set, strut spreader tool, torque wrench, and safety glasses.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel for access to the strut assembly.

2. Remove the Old Strut

Disconnect the sway bar link:
- Use a wrench to remove the nut from the sway bar link connected to the strut.
Remove the lower strut bolt:
- Locate the lower strut bolt and remove it using a socket and ratchet.
Detach the strut from the top mount:
- Open the hood and locate the strut top mount.
- Remove the nuts securing the strut to the mount using a socket.
Extract the strut:
- Carefully pull the strut down and out from the lower control arm and set it aside.

3. Install the New Strut

Position the new strut:
- Align the new strut with the lower control arm and insert it into place.
Secure the lower strut bolt:
- Insert and tighten the lower strut bolt to the manufacturer’s torque specification (usually around 85 ft-lbs, but check your service manual).
Attach the strut to the top mount:
- Place the strut into the top mount and secure it with the nuts. Tighten to the specified torque (typically between 22-30 ft-lbs).
Reconnect the sway bar link:
- Reattach the sway bar link to the strut and tighten the nut to the specified torque.

4. Reassemble

Reinstall the wheel and tighten the lug nuts to the manufacturer’s specification (usually around 100 ft-lbs).
