Solution

1. Preparation

Gather Tools and Parts: Obtain necessary tools and replacement parts.
Safety Precautions: Ensure the vehicle is parked on a flat surface, engage the parking brake, and use wheel chocks.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to gain access to the strut assembly.

4. Inspect the Strut

Check the strut for any visible oil leaks or damage.
If oil is present, the strut is likely leaking and requires replacement.

5. Replace the Strut (if leaking)

Remove the Old Strut:
- Disconnect the strut from the upper mounting points (may require access through the engine bay or under the dashboard).
- Remove the lower mounting bolts connecting the strut to the knuckle.
Install New Strut:
- Position the new strut in place.
- Reinstall the lower mounting bolts and torque them to manufacturer specifications (typically around 60-80 Nm, check specific values).
- Reattach the upper mounting points.

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value (usually around 120 Nm).
