Solution

1. Preparation

Tools Required: Jack, jack stands, wrench set, torque wrench, strut spring compressor (if replacing struts).
Ensure the vehicle is parked on a flat, level surface and the engine is off.
Disconnect the battery if electrical components will be handled.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which strut is leaking.
Secure the vehicle with jack stands to ensure it is stable before proceeding.

3. Remove the Wheel

Use a wrench to loosen the lug nuts on the wheel corresponding to the leaking strut.
Remove the wheel and set it aside.

4. Disconnect the Strut

Remove any bolts securing the strut to the control arm using a wrench.
Detach the upper strut mount from the vehicle body (may require removing additional components for access).
Keep track of all fasteners for reinstallation.

5. Inspect and Replace

Check the strut for damage. If leaking, use a strut spring compressor to safely compress the spring.
Remove the old strut and replace it with a new or refurbished unit. Ensure that the new strut matches OEM specifications.
Reassemble the strut by reattaching the upper mount and securing it with the bolts.

6. Reinstall the Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.

7. Final Checks

Reconnect the battery and perform a test drive to ensure proper functionality and check for any unusual noises or handling issues.
