Use a jack to lift the front or rear of the vehicle, depending on which struts are leaking.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel where the strut is leaking.
Place the wheel aside.

4. Remove Strut Assembly

Disconnect Components:
- Remove any brake line brackets or sensors attached to the strut.
- Detach the sway bar link from the strut.
Remove Strut Mount Bolts:
- Open the hood and remove the strut top mount nuts using a socket wrench.
Lower the Vehicle:
- Carefully lower the vehicle slightly to detach the strut from the lower control arm.
Remove the Strut:
- Pull the strut assembly out from the wheel well.

5. Replace Strut

Compare the new strut with the old one to ensure compatibility.
Install the new strut by reversing the removal process:
1. Position the strut into the lower control arm.
2. Secure the strut with the lower bolts and torque to manufacturer specifications (check service manual for exact torque values).
3. Reattach strut mount nuts in the engine bay, ensuring they are torqued correctly.

6. Reconnect Components

Reattach the sway bar link and any brake line brackets or sensors removed earlier.
Ensure all components are securely fastened.

7. Reinstall Wheel and Lower Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle fully and torque the lug nuts to the manufacturer’s specifications.
