2nd Gen Non-Engine/Transmission New Steering box and PS pump??? Something failed.

On my 2000 3500 6-speed. The stock steering box had some play and was leaking along with the PS pump. I bought a reman box and pump from NAPA. Got them both installed front end off the ground on jack stands. Was cycling the wheel from lock to lock to bleed the air. Started the truck and had someone in the cab to cycle the wheel while I watched the fluid level. The PS was just starting to work and all was good. While turning to the left truck running still on jack stand there was a pretty loud pop. I could see the cap on the steering box was sucking in and popping. I figured something fails inside the box. NAPA gave me a new box no charge and I got it installed. I'm having some trouble getting everything to work. Could the PS pump be what failed? I can look into it and see the fluid churning and if I crack the lines to the hydroboost I get fluid pouring out but have no idea on what pressure it is. Any way to check or test the PS pump? Hydroboost was replaced about a year a go. RPM doesnot seem to effect the steering and if I stand on the brake I do not get the crowl or grown from pressing the peddle to the floor. Can the pump be moving fluid but just not making enough pressue or flow? Only thing I haven't replaced is the PS lines but stock lines look good with no know leaks. Any ideas what's going on?

UPDATE. I pulled the PS pump off and took off the reservoir. Where one of the bolts that hold the reservoir on there is a crack running from the taped hole in the casting and it runs about 1/3 the way around the pump. I'm assuming the loud pop was the pump cracking. Its obvious the pump failed but did it make to much pressure and crack itself or did the box fail causing the pump to crack. The box would still turn but it got significantly tighter and stiff right after the pump broke. Wandering if some broken metal went into the box. Both the pump and steering box were new remans with less than 5 mins of run time at idel.

Did you get the spacers put back in the right place might be one of them was put in wrong and caused it to break.

The high failure rate of reman PS pumps is the reason I finally bit the bullet and bought a new one from Dodge. Now instead of replacing 5 in one year I have gone 5 years without replacing one.
