Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the opposite wheels.
Disconnect the battery negative terminal to prevent electrical issues.

2. Lift the Vehicle

Use a floor jack to lift the front or rear of the vehicle as necessary.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Wheel

Use a lug wrench to remove the wheel that corresponds to the leaking strut.
Place the wheel in a safe location.

4. Remove the Strut Assembly

Disconnect the sway bar link: Use a socket wrench to remove the nut securing the sway bar link to the strut.
Detach the strut from the brake line: Carefully unclip the brake line from any retaining clips on the strut.
Unbolt the strut from the steering knuckle: Remove the bolts securing the strut to the knuckle using a socket and ratchet.
Remove the upper strut mount: Access the upper strut mount inside the engine bay or trunk (depending on the strut location), and remove the nuts using a socket.
Carefully pull the strut assembly out of the vehicle.

5. Replace the Strut

Install the new strut: Position the new strut in the strut tower and align it with the upper mount holes.
Secure the upper strut mount: Thread and tighten the nuts onto the upper mount, torquing to the manufacturer's specification (typically around 30-50 ft-lbs).
Reattach the strut to the steering knuckle: Insert the strut into the knuckle and replace the bolts, torqueing them to manufacturer specifications (usually around 80-100 ft-lbs).
Reconnect the sway bar link: Position the sway bar link and secure it with the nut, torquing it appropriately (usually around 20-30 ft-lbs).
Reconnect the brake line: Ensure the brake line is clipped back into place securely.

6. Reassemble and Test

Replace the wheel and tighten the lug nuts to the manufacturer's specifications (typically around 76-85 ft-lbs).
Lower the vehicle back to the ground and reconnect the negative battery terminal.
Perform a bounce test to ensure proper strut function.
