Ive got a 93 cherokee with a 4.0. The freeze plugs rusted out, so after an afternoon covered in grease, I put it all back together again sans antifreeze pouring out all over my driveway. Now I start it up and go around the block when my power steering starts to whine. I think to myself, "Well, guess I have to bleed the power steering." So after bleeding the power steering 3 different times, replacing the hoses, and beating my head against the wall Im out of ideas. Im really wondering why people say that foaming power steering could be pinhole leaks in your lines as the pressure side operates at a psi which would be forcing fluid out faster than air could enter, and the return line just dumps into the reservoir. I cant see how the lines could cause aeration, but i replaced them as I thought maybe they knew some physics i didnt. As soon as I start the vehicle the power steering fluid turns to foam and gushes all over the place. The only thing it could possible be is a suction side seal in the pump, or some kind of leak in the steering box. Does anyone have any ideas?
I dont understand how unbolting and moving the pump out of the way caused it to turn into Mr Bubbles? Anyone?
