2000 Buick Lesabre Custom, high miles. Fluid on hoses below power steering pump reservoir and some on ground. Reservior appears full when checked. Fluid is dark. Whining while driving, seems to go away once shifts into fourth gear (automatic). Starting to feel occasional vibration or shudder for one to two seconds at a time while driving at 20+ mph. Is it the power steering pump?

power steering reservoir is full. on this engine it is a direct drive power steering unit (no serpentine belt on it), it must run right off the top camshaft of the engine? Im getting a crunchy/grinding feel when turning extreme left. You can feel it thru steering wheel. There are no obvious fluid leaks anywhere. Would this be a rack and pinion issue?
The power steering starts working again a short time later.
power steering pump & steering gear have been replaced, fluid been flushed
line leaking on bottom of power steering pump. will not tighten
