1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid siphon, new power steering fluid (Porsche approved).
Remove the power steering reservoir cap and inspect the fluid level.
If low, siphon out old fluid and refill with new power steering fluid until it reaches the appropriate level.
Reinstall the cap securely.

3. Replace Worn Steering Components

Tools Required: Socket set, torque wrench, ball joint separator, and new steering components (as needed).
Lift the front of the vehicle and secure it on jack stands.
Remove the front wheels to access suspension components.
Using a ball joint separator, remove any worn ball joints or tie rods identified during diagnostics.
Install new components, tightening to manufacturer’s specified torque values.

4. Replace Wheel Bearings (if necessary)

Tools Required: Bearing puller, socket set, and new wheel bearings.
Remove the wheel hub assembly by taking off the wheel and unbolting the hub from the suspension.
Using a bearing puller, carefully extract the old wheel bearings.
Install new wheel bearings, ensuring they are seated properly and lubricated.

5. Reassemble and Test

Reassemble all components in reverse order of disassembly.
Reinstall the wheels and lower the vehicle.
Connect the battery and check for proper steering operation without any noise.
