Loud groaning noises from steering system

I have a 97 Grand Prix GTP with 191,000+ miles. For the past couple of months, I have had a loud groaning sound coming from somewhere under the hood when I steer the car in either direction. This groaning is most noticeable at idle or very low speeds and when the car is first started up in the morning. It seems to get less noticeable at higher speeds and after the car has warmed up a while. Over the past few days, at idle/low speed and when cold, there is now more resistance when steering in either direction. Power steering pump or rack and pinion? (Hoping this is more PS pump than rack and pinion). The rack and pinion was replaced in 2009. Thanks

Noise is usually due to air in the system. Have you checked the fluid level? You may have a power steering leak causing the noise.

Yeah I would say it would be the pump, as in not getting enough fluid inside the pump. Check levels of steering fluid, and post back with results. (BTW Lucas powersteering treatment is freaking awesome) I doubt its the rack aswell.
