Could the problem be that during a low speed turn with your foot on the brake and the a/c on and the pwr steering pump working hard (hence turning into a spot) that the engine is dragging down to such a low rpm due to all the conditional loads (a/c, turning sharply, foot on the brake etc.) that the engine almost attempts to stall and the result is that the pwr steering pump squeals slightly and causes a sensation in the steering wheel itself due to momentary loss of hydro pressure. The computer/ecu/dme (whatever you want to call it) corrects the low idle in time to not let the engine stall but the result is the squeal/thump in steering wheel?
Just a thought
