Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel corresponding to the leaking strut using a socket set.

3. Remove the Strut Assembly

Support the strut with a jack.
Remove the bolts securing the strut to the steering knuckle using a socket set.
Disconnect any brake lines or sensors connected to the strut if necessary, ensuring to mark their positions for reinstallation.
Remove the upper strut mount bolts from the engine bay or under the dashboard, depending on the design.

4. Replace the Strut

Install the new strut by reversing the removal steps.
Ensure the upper strut mount is torqued to the manufacturer’s specifications (typically around 20-30 Nm, check specific values for the model).
Reattach any brake lines or sensors, ensuring they are secure and correctly positioned.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications (usually around 100-120 Nm).

6. Final Checks

Reconnect the battery.
Perform a test drive to ensure proper operation and check for any leaks.
