Remove the lug nuts using a socket and impact wrench.
Take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

4.1. Disconnect Brake Lines and Sensors:
- Carefully disconnect any brake lines or sensors attached to the strut.
4.2. Remove Strut Mount Bolts:
- Locate and remove the bolts securing the strut mount to the vehicle chassis using a socket set.
4.3. Detach the Lower Strut Bolt:
- Remove the lower strut bolt connecting the strut to the lower control arm.
4.4. Take Out the Strut:
- Carefully pull the strut assembly from the vehicle.

5. Replace the Strut

5.1. Compress the Spring:
- Use a strut spring compressor to safely compress the spring on the old strut.
5.2. Remove the Old Strut:
- Unscrew the top nut and carefully remove the spring from the old strut.
5.3. Install New Strut:
- Position the spring onto the new strut and secure it with the top nut, ensuring it is torqued to the manufacturer's specifications (typically around 18-22 ft-lbs).

6.3. Reconnect Brake Lines and Sensors:
- Reattach any brake lines or sensors that were disconnected.

7. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications (typically around 75-80 ft-lbs).
