Power Steering problem, can use some input on whats going on.

Do you have instructions for installing a new pump? You may not since you are using your old one. The instructions say you MUST flush your old system of all old fluid, or the warranty will be void. They also suggest cranking the engine in short bursts to circulate fluid and allow trapped air to go the reservoir. I suggest re-flushing your system to make sure all dirt and trapped air are gone.
