2000 voyager power steering noise

I had the steering rack replaced at 45k miles. Now at 70, I was low on
powersteering fluid. I put some in and still hear a noise when I turn
the wheel. I have not seen any leaks. Does anyone know what this might
be ?

 

I know it is not a Chrysler but Ford for years was having problems that they
could not figure with some Taurus's that had power steering noise. Kind of
a hiss all the time when wheel turned even slightly. I had a Taurus without
the sound and after a leak was fixed it started making the sound and the
dealer told me it was normal. I did not pursue it because I sold the car
but years later I read that Ford finally figured out that kinking power
steering hose caused the excess noise. How stupid are they that it took
years to figure that out. Anyway you did not discribe the noise. If a hiss
maybe my kink idea might help.

 

Thanks, a friend of mine mentioned fords. I will look at the hose. It
is hard to believe that I am the only one with such a problem.
