Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Inspect and Top Off Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Check the fluid level against the markings on the reservoir.
If low, add the recommended power steering fluid type (Porsche specifies CHF 202, or equivalent).

3. Examine Steering Components

Use a jack and jack stands to lift the front of the vehicle for better access.
Inspect the tie rods and ball joints for any signs of wear or damage, such as cracks or excessive play.
Replace any worn components with OEM parts if necessary (tools: socket set, torque wrench).

4. Check Suspension Components

Inspect the suspension bushings for deterioration or cracking.
Replace any damaged bushings (tools: socket set, pry bar).
Tighten any loose bolts to the manufacturer's torque specifications.

5. Test Drive

Reassemble any components removed during inspection.
Conduct a test drive to evaluate if the noise persists while turning under various conditions.
