What would cause a moaning sound from the front of the engine on a 1993 Maxima?

Answer 1

check the power steering pump

check the power steering fluid level. If you need to add fluid, use Dextron III. After you add to full line, let is sit with the cap off for 30 minutes or so DO NOT start the engine.

Then "bleed" the power steering system:

1. replace the cap
2. raise the front end so that both wheels are off the garage floor - BE SURE to secure the rear wheels with chocks and pull up the park brake
3. start the engine
4. with light pressure, turn the steering wheel all the way counterclockwise and hold for several seconds
5. turn back past center and all the way clockwise and hold for several seconds
6. repeat 4-5 several times
7. Turn off the engine and check fluid level, add to full if necessary.
8. lower the front end so that the tires come in contact with the floor but not all the way down
9. Restart the engine repeat steps 6-7 several times
10. return to center and turn the engine off
11. lower the front end completely

Hope this reduces your noise as much as it did mine. I also added about 2 ounces of friction reducer - worked wonders.
