 I have posted about this growling noise in the power steering on startup since 2006.  I searched my history and have 7 topics I've posted about this to try to resolve it.  I finally got a knowledgeable tech from BAB steering and he assured me my pump was good and that somewhere there is a leak or another source of an air lock.  I told him the reservoir location height is really close to the pump height, so I suggested I could raise it higher in the engine room.  He thought that was a good idea, and he recommended a suction hose change that will not collapse.  Also, T clamps only on that hose. 

I moved the reservoir up high in the engine bay, found some Aeroquip type hose with a wire coil to make it stiff and T clamps.  Relocated the hoses, tied everything tight and out of the way of the radiator fan, and refilled with ATF.  The first engine run had lots of noise and took almost a gallon of ATF to get the system back to normal.  The noise finally stopped after the system purged the air. 

That was 2 weeks ago.  Today was the first test.  Started up the coach and oh my, no noise, no fluid blown overboard, no ATF all over my back end ;D  Finally, something I tried worked.  I hope I put this to rest for good.  13 years of this annoyance is too many. :o

Below is a picture of the relocated reservoir.  It is about the same level of my radiator surge tank.

Maybe one of the hoses in original position had an air trap in it. Glad to hear you fixed it.
