Sounds can radiate from different areas, what I thought was in the rear, was actually up front. More than likely this is a typical sound coming from your swaybar end links. You have 2 up front, and 2 in the rear., front ones normally go out first. Grab a hold of it and try shaking them, should be tight. When replacing them, get ones that are greasable. OEM didn't have that option. Try rocking the truck back and forth to try and replicate the sound.
I wish I could upload a video of the sound it does. .pretty sure it is the heating shield
My 2020 blazer rattles too. When driver side window open and doing like 30 or 40 a min or two later back hatch rattles. Seems like design floor very annoying and can be loud. Basically cant drive my brand new car with window open unless I want loud rattle . Very disappointed in chevy!
