Noisy steering

[anthony@xxxxxxxxxxxxx]

Hi Everyone;

I have a question. On my 56 Imperial whenever I am stopped and turning to 
back up or pull forward the power steering unit squeals like it is out of 
fluid. It only does it then no other time. Now last year I had to remove 
the power steering unit to get the generator rebuilt. After I put the power 
steering unit on it started the squeal stated above. I did flush it out 
again, disconnect the hose and turn it over. I then put new fluid back in 
and it still did it. Any ideas?
