Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; it should be within the recommended range.
If low, add the manufacturer-recommended fluid type (Porsche CHF 202).

3. Inspect and Repair Leaks

Visually inspect hoses, connections, and the steering rack for any signs of leaks.
If leaks are found, replace the damaged hoses or steering rack as needed.
Tighten any loose connections to prevent further fluid loss.

4. Replace Power Steering Pump (if necessary)

Remove the drive belt from the power steering pump using a socket wrench.
Disconnect the power steering lines from the pump.
Unbolt the pump from its mounting location and remove it.
Install the new power steering pump and reconnect the lines, ensuring a tight fit.

5. Align the Steering Wheel

If the steering wheel is misaligned, adjust the tie rods accordingly.
Measure the alignment angles using a laser alignment tool.
Adjust each tie rod until the steering wheel is centered when driving straight.
