I found out what the moaning sound was, coming from the right side of the car, when the wheel was turned hard left. It sounded like plastic rubbing, and seemed to be coming from under the dash area.
It was the idler arm bushing, very obvious when the tie rod is disconnected and drag link pulled hard left. The bushings are attached to a tube welded to the floorpan, so the sound would telegraph up as if it was under the right side of the dash.
Hope this tidbit is useful to someone. The repair kit is under $20.00, and takes about an hour to install.
