I have a 2015 Acadia (92k miles). In the past couple of weeks, I have noticed a slight groaning or "moaning" sound when I let off the gas pedal, at slow speeds (less that 35mph). When making a 90 degree right hand turn, it is a little more noticeable. The sound almost sounds like a chair scooting across a hard floor, if that makes sense. Here's a couple "videos" of the sound.



A little back history.......In May, I had to replace the high pressure line for the power steering. About a week after that, I had to replace the power steering pump.
About a week after that I had to have the pump because it was making a groaning sound that turned out to be a bad bearing. It was obviously warrantied.
So, I'm wondering if it is indeed the pump again or something else?
Thanks in advance

Listening around the engine bay with a mechanic's stethoscope may be able to tell you where the noise originates.
