I just finished changing out my old steering box, for a new quick ratio box.
I disconnected the hoses from the pump where they go into the box, and had them up high so they would not drain. I swaped out the box, which came full of fluid from the manufacturer, I reconnected the lines and topped off the fluid.
With the front end off the ground, I started up the car and turned the wheel, left and right, all the way.
I am now getting a grinding noise from the pump(?), and the fluid inside the reservoir is all foamy. Do you think this is normal and will stop once the fluid circulated around?
Something wrong?
