Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Lift Vehicle

Use a hydraulic 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 Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the strut assembly.

4. Remove Strut Assembly

Disconnect any brake line or sensor wire connected to the strut.
Remove the bolts securing the strut to the steering knuckle using a socket.
Remove the upper strut mount bolts located in the engine bay or under the rear seat (depending on strut location).
Carefully detach the strut from the vehicle.

5. Replace Strut

Install the new strut by reversing the removal steps.
Ensure the strut is properly aligned and torque all bolts to the manufacturer's specifications (check service manual for exact torque values).
Reattach any brake lines or sensors that were disconnected.

6. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque.

7. Test and Adjust

Lower the vehicle completely and check the ride height.
Test the suspension by pushing down on the corners and ensuring proper rebound.
Perform a test drive to confirm the repair has resolved the issue.
