Locate the top strut mount, typically under the hood or in the trunk, and remove the nuts securing the strut using a socket wrench.
Remove any necessary components obstructing access to the bottom of the strut.
Unscrew the bolts securing the strut to the lower control arm or knuckle using a torque wrench.
Carefully pull the strut assembly out of the vehicle.

5. Replace Strut

Install the new strut by reversing the removal process.
Ensure the strut is properly seated in the lower control arm and secure it with the appropriate torque specification (consult service manual for specific torque values).
Reattach the top mount and ensure it's securely fastened.

6. Reassemble Vehicle

Reinstall any components that were removed to access the strut.
Put the wheel back on and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Remove the jack stands and lower the vehicle using the hydraulic jack.
Tighten the lug nuts to the manufacturer's specified torque value.
Reconnect the negative battery terminal.
