Solution
1. Preparation
  • Gather tools: socket set, torque wrench, power steering fluid, OBD-II scanner.
  • Ensure the vehicle is on a level surface and safely secured with jack stands.
2. Check and Refill Power Steering Fluid
  • Locate the power steering reservoir.
  • Remove the cap and check the fluid level.
  • If low, add the appropriate type of power steering fluid as specified in the owner's manual.
  • Replace the cap securely.
3. Inspect Power Steering Pump and Hoses
  • Visually inspect the power steering pump for any signs of leaks or damage.
  • Check hoses for cracks or loose connections; tighten any loose fittings.
  • If leaks are found, replace the affected hoses or pump.
4. Replace Power Steering Pump (if necessary)
  • Disconnect the negative battery terminal to prevent electrical issues.
  • Remove the drive belt from the power steering pump.
  • Unbolt the power steering pump from its mount using the socket set.
  • Disconnect the hoses from the pump, capturing any fluid in a catch basin.
  • Install the new power steering pump by reversing the removal steps, ensuring all connections are secure and tight.
  • Reattach the drive belt and check for proper tension.
5. Final Checks
  • Reconnect the negative battery terminal.
  • Start the engine and turn the steering wheel from lock to lock to purge air from the system.
  • Check fluid levels again, topping off as necessary.
