Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the 12V battery to ensure safety while working on electrical components.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Remove the power steering fluid reservoir cap.
- Check fluid quality; if it appears dark or contaminated, proceed with a fluid change.
- Drain old fluid by disconnecting the return line from the steering pump into a catch pan.
- Fill the reservoir with new power steering fluid as per manufacturer specifications (Tesla recommends a specific fluid type).

3. Remove and Replace the Steering Pump (if defective)

Tools Required: Socket set, torque wrench, fluid catch pan, rags, new power steering pump, new O-rings/seals.
Sub-steps:
- Locate the steering pump, typically near the front of the vehicle's engine compartment.
- Disconnect the electrical connector from the steering pump.
- Remove the high-pressure and return lines from the pump using the appropriate socket.
- Unscrew the mounting bolts securing the pump and remove the pump from its bracket.
- Install the new steering pump in reverse order of removal. Ensure all bolts are torqued to manufacturer specifications.
- Reconnect the fluid lines and electrical connector.

4. Bleed the Steering System

Sub-steps:
- Refill the power steering fluid reservoir with the recommended fluid.
- Start the vehicle and turn the steering wheel from lock to lock several times to eliminate air bubbles from the system.
- Check fluid levels and top off if necessary.
