- Strut spring compressor
- Screwdriver set
- Pliers
- Safety glasses and gloves
Safety Warnings:
- Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Remove the Wheel

Loosen the lug nuts on the wheel where the strut is leaking.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Disconnect the brake line if it's attached to the strut using a screwdriver or pliers.
Unbolt the sway bar link from the strut using the socket set.
Remove the bolts securing the strut to the lower control arm.
Open the hood and remove the bolts securing the strut mount to the vehicle body using a socket set.
Carefully pull the strut assembly out of the vehicle.

4. Replace or Repair the Strut

If replacing, use a strut spring compressor to compress the coil spring on the old strut.
Carefully remove the upper strut mount and any associated components.
Install the spring onto the new strut, ensuring all components are properly aligned.
Reassemble the strut mount on the new strut, tightening to manufacturer specifications.

5. Reinstall the Strut Assembly

Position the strut assembly back into the vehicle.
Secure it by tightening the bolts to the upper mount and lower control arm to the specified torque values (consult the service manual for specific torque specs).
Reconnect the brake line and sway bar link.

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.

7. Final Checks

Inspect the area for any leaks or loose components.
Test drive the vehicle to ensure proper handling and that no noises occur.
