i ruled out suspension (just about totally rebuilt anyway), wheels (same), and motor mounts before going to the Indy. They confirmed the above and eventually landed on a worn power steering pump. Haven't done any work yet and they seem a bit unsure so don't want to throw money at noises just yet.


What's the temp ambient? When cold my wife's power steering sounds exactly like "whales humping" until friction warms up the fluid. It was a little low and topping off made it better.

A put put put sound sounds like a sticking ball joint. You said most were replaced. Take an audio recording and share (video will include sound). If a joint not usually too difficult to find. Have somebody turn the wheel to reproduce the sound and put your hand on the various joints. A stick-slip joint will have a distinct vibration.
