Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which strut is leaking.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to remove the wheel nuts.
Take off the wheel to access the strut assembly.

4. Disconnect the Strut

Remove the bolts securing the strut to the steering knuckle using a socket set.
Detach the strut from the upper mount by removing the nuts on the top of the strut tower.
Carefully pull the strut assembly out of the vehicle.

5. Install New Strut

Position the new strut in place of the old one.
Secure the strut to the upper mount using the original nuts, torquing them to the manufacturer’s specifications (typically 30-40 ft-lbs).
Reattach the lower strut bolts to the steering knuckle, ensuring they are also torqued to the manufacturer's specifications.

6. Reassemble the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications (usually 70-90 ft-lbs).

7. Final Check

Inspect for any leaks and ensure all bolts are tightened properly.
Test the suspension by pressing down on the vehicle to check for proper rebound.
