Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Identify and Replace Leaking Components

Fluid Reservoir
- Remove the cap and inspect for cracks; if damaged, replace it with a new reservoir.
Hoses and Lines
- Detach the affected hoses from the power steering pump and rack.
- Replace any cracked or damaged hoses with new ones.
Steering Rack
- If fluid is leaking from the steering rack, remove it from the vehicle. Replace with a new unit if necessary.
- Ensure the new rack is properly aligned and secured.
Power Steering Pump
- Remove the power steering pump if it shows signs of leakage.
- Replace it with a new pump, ensuring all connections are tight.

3. Refill and Bleed the Power Steering System

Refill the power steering fluid reservoir with the appropriate fluid (typically ATF or a specific Tesla-approved fluid).
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check the fluid level again and add as necessary.

4. Final Assembly

Reconnect the battery.
Ensure all components are securely fastened.
Inspect for any leaks after the repair.
