Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Strut spring compressor
- Screwdrivers
- Pliers
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported by jack stands before starting work.

2. Remove the Wheel

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

3. Disconnect the Strut

Remove the bolts securing the lower end of the strut to the control arm using a socket wrench.
Detach any brake line brackets or sensors that are connected to the strut.
Inside the engine bay, locate the upper strut mount and remove the nuts securing the strut using a socket wrench.

4. Remove the Strut Assembly

Carefully pull the strut assembly out from the strut tower and lower control arm. It may require some maneuvering due to the spring tension.

5. Replace the Strut

If reusing the spring, use a strut spring compressor to compress the spring before removing it from the old strut.
Install the spring onto the new strut and ensure it is seated correctly.
Reinstall the upper strut mount and secure it with the nuts, tightening to the manufacturer's specifications.

6. Reinstall the Strut Assembly

Position the new strut assembly back into the strut tower and lower control arm.
Secure the lower strut bolts and torque them to the specified value.
Reconnect any brake lines or sensors to their original positions.

7. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
