Power Steering k10
Ran across one with a pinched return line, someone force-bent the return line at the box causing the line to be pinched, not fully closed off, just restricted. There was no fluid in it because I guess it all came out the cap.
Swapped the line for a non-kinked one and topped off fluid. Ran truck, stopped truck after a few seconds, topped off again, repeated once more. Turned wheels left and right a few times, no assist. Had no floor jack but was on a smooth surface. Turned truck off, fluid poured out of cap and all over the floor. Chattered a couple of times when turning but never assist. Tried a couple more times, same results. My thoughts were it is a new box AND pump but something wasn't right. Maybe the box wasn't done right or the valve for the pressure side on the pump was messed up. Didn't go any further after that though. Thoughts?

Re: Power Steering k10
That symptom is usually associated with a restricted line. Pressure builds but cannot circulate back to the pump.

Re: Power Steering k10
Yes that is what I thought and I remedied the kink in the line, but it still spit fluid out after that.

Re: Power Steering k10
I fought a similar situation with my build a few months back. With wheels off ground, I would get a little assist when turning right but nothing to the left and the pump chattered like it was going to explode. When I turned off engine, fluid would boil out of the pump. Same as you I had new steering box and pump. What I did was (tires off ground) first, turn wheel right to left with engine off. I went from lock to lock with engine off. Then I let truck run without trying to turn for a few minutes, then I very slowly turned steering to right to the lock, then back to left. If it fought me, I would let it run at idle without trying to turn for a couple of minutes. I did this for a few cycles and the steering got better each time. Now it turns with no effort with tires on ground. I think it took all this to get all the air out and bled 100%.
