why does my Genesis G70 make a hissing noise when I turn the steering wheel?

Solution

1. Preparation

• Collect necessary tools and components.
• Ensure the vehicle is on a level surface and securely lifted if needed.
• Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Check and Refill Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level. If low, add the appropriate type of power steering fluid (refer to the owner’s manual for specifications).
• Inspect the fluid for contamination or discoloration, and replace if necessary.

3. Inspect and Replace Power Steering Pump (if needed)

• If the pump is identified as the source of the noise:
  • Disconnect power steering lines from the pump using a wrench.
  • Remove the mounting bolts securing the power steering pump.
  • Replace the pump with a new one, ensuring proper alignment.
  • Reconnect the power steering lines and tighten to the manufacturer’s specifications.

4. Examine and Replace Steering Rack (if needed)

• If issues point to the steering rack:
  • Remove the steering column connection and any necessary components obstructing access to the rack.
  • Disconnect the power steering lines from the steering rack.
  • Remove the mounting bolts securing the rack.
  • Install the new steering rack, ensuring proper alignment.
  • Reconnect the power steering lines and tighten securely.

5. Refill and Bleed Power Steering System

• After any repairs, refill the power steering fluid reservoir to the correct level.
• Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
• Check for any leaks.
