| FAQ_Q1 | Why is the pump making a whining noise all of the time? |
| FAA_A1 | A whining pump is usually caused by air in the power steering system. Inspect the reservoir for proper fluid level. If fluid has foam or air bubbles present, air has entered the system or has not been properly bled (ensure all hoses/clamps are tight). Some systems require special vacuum bleeding procedures. |
| FAQ_Q2 | Why do I still have hard steering in one direction after I replaced the pump? |
| FAA_A2 | The problem is most likely in the steering unit-the pump does not know left from right. Check for binding steering components and repair as necessary. |
