ml320 1999 just turned 400000 miles

half a million or bust, need an opinion. lost power steering at an idle, there was none until you got up to about 1000 rpm, soooo i replaced the pump myself, solved that problem but it constantly whineing at low rpm when turning, or at idle turning, system bled repeatedly, no air left,, drove another 1000 miles , very small leak one drop over night at most turned out to be the cooling hose on the radiator loose,,, tightened, drove another thousand no change still whines.,,, H E L P,,, could it just be a bad pump? bought rebuilt off ebay for 99.00 so im thinking that i got what i paid for, but if there was a problem with the system i can only thing a whine has to be the pump,, any imput would be greatly appreciated, dont want the headache of putting on another pump time and expense if thats the wrong thing.. any help?? thanks Newvisionss oh yea,,, also replaced the resovoir and O ring with a decent factory replacement, no cheap, did the twenty turns with wheels off the ground, sucked out fluid and put in new, did this twice to make sure there was no sign of air,,,
