Question about 1992 Chevrolet Lumina APV
Power steering noise
When the fluid is low and you add some ... it still needs more after
you run it for awhile. The reason for that is that the pump pumps the
fluid through the lines and gets out the air in them. Keep filling and
checking after you start the car and turn the wheel from side to side
all the way.
1. Know what type of power-steering fluid is needed for your car. Some power-steering pumps can use automatic transmission fluid, others have specific power-steering fluid for each car i.e. Honda requires and suggests that you use Honda's brand power-steering fluid (see owner's manual). Make sure you know, or the warranty from the dealership or from the parts store may be voided.
2. Before attaching the power-steering belt, fill pump with required amount and type of fluid, (see owner's manual) and turn the pulley wheel by hand a few times. This helps cut down on dry turns before they can happen. If more power-steering fluid is needed fill accordingly.
3. Attach the power-steering belt with proper amount of tension (see owner's manual).
4. Turn vehicle on and proceed to turn the steering-wheel all-the-way right and left 3-4 times.
5. Turn the vehicle off and examine that the belt tension is acceptable, and again check the level of fluid and fill accordingly.
6. Always, always check your owner's manual before performing any maintenance on your vehicle. An educated car owner is a safe car owner!
Another possibility How long has the pump run without fluid for? There could be damage inside to the cam an rotor (assuming it's is a vane type pump), to the plates or it could be cavitating due to the ingress of air - possibly why the fluid leaked out in the first place.

Check all lines. I had the problem of the steering was hard to turn. I replaced the pump and all is well. I had to bleed the system.
Jack the front end so that the tires are off the ground and then turn the wheels all the way to the left and then to the right. Do this about 20 times but make sure to check the fluid after about three or four full turns. Keep the fluid up. After the fluid looks clear, no bubbles, then put the car on the ground and try out the new steering. I would check the fluid after you turn it a few times it might need a little.
