Thoughts:

. See if you have a Power Steering Pressure (PSP) Switch. The PSP sensor is an hydraulic pressure switch in the power steering system. When the switch closes, the ECM receives an input signal that causes it to maintain engine speed under high steering loads during parking. This switch signal also causes the ECM to increase transaxle hydraulic line pressure during low-speed vehicle maneuvers.

. Check power steering fluid. If it's dark or thickened, it should be changed right away. Valvoline SynPower Power Steering Fluid is a partial synthetic power steering fluid approved for GM applications. I recommend changing power steering fluid regularly, since it's the easiest way to prevent very expensive repair bills.

. Listen to power steering pump with a mechanic's stethoscope, while the engine is running.

. Examine serpentine belt and tensioner.

I love that question.

If you took it in to my mechanics they'd probably just tell you it's all in your head! (I'm sure that's what they were thinking about my steering wheel shake).
