my Tesla Model S has a hard steering when cold what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the brake is engaged.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check Power Steering Fluid

• Locate the power steering reservoir.
• Remove the cap and check the fluid level; it should be between the "min" and "max" marks.
• If low, top off with the manufacturer-recommended power steering fluid.

3. Inspect Power Steering Pump

• Remove any covers obstructing access to the power steering pump.
• Check for any visible leaks around the pump and hoses.
• If the pump is noisy or leaking, replace it using the following sub-steps:
  • Disconnect the hoses from the pump, using a wrench to avoid damage.
  • Unbolt the pump from its bracket and remove it.
  • Install the new pump and torque the bolts to manufacturer specifications.
  • Reconnect the hoses securely.

4. Inspect and Replace Steering Rack (if necessary)

• If the steering rack shows signs of wear or damage, follow these steps:
  • Safely lift the vehicle and secure it with jack stands.
  • Remove the front wheels for better access to the steering components.
  • Disconnect the steering linkage from the rack.
  • Unbolt the steering rack from its mounts and remove it.
  • Install the new steering rack and torque the bolts as per manufacturer specifications.
  • Reconnect the steering linkage and reinstall the wheels.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and turn the steering wheel side to side to bleed any air from the power steering system.
• Check for any leaks and ensure the steering feels normal.
