After removing my reman power steering fitting, valve, and spring, there is a difference in spring length. I swapped all 3 pieces out from under the car. It was a little messy but easy. It seems to be working ok at the moment. It does make a very light noise when I turn the wheels. Sounds like they do when they are low on fluid. It is faint and that may be the way they are. I don't know. With it sitting at idle, I can turn the wheel and the rpm drops a little until I stop turning the wheel. Guess I need to see if my El Camino makes the noise and drops rpm as well. Now that I'm really looking and listening for something this just could be normal and I've never noticed. I will take it for a drive later. I have installed countless reman power steering units through the years and this is my first problem with one.
