Wierd noise

[denalilove86]

my 2013 yukon denali started making what sounded like a alternator bearing noise and so I replaced the alternator then still the noise was there then I thought has to be my power steering pump so I replaced that still getting this noise that sounds like a exhaust shroud is getting touched by something but that can't be does this sound like a transfer case issue does it v

I would suggest recording a video with your phone and upload it to youtube and then post a link here and we can help you narrow it down hopefully. probably best to invest in a $5 stethoscope to find it rather than just throwing parts at it.
make the video longer than a couple seconds..... so many people make the shortest video possible and that doesn't help one bit.....
move your phone around the engine bay and maybe under the vehicle to help pinpoint the source.

Welcome to the forum from Oregon. Yes, record and post a video here. Likely go thru you tube and post the link.

tensioner/idler pulley are in the area and worth a check. (cheap and easy to replace!)

Water Pump (bearing) could also be making noise along with anything in
the serpentine system too... idler pulley, tensioner(mentioned above) etc
You can take off the belt(s) and start it and run for a very brief time and that
would rule out or in things in the belt system
