Firewall buzz sound completely gone.
After rotating the heater hose to the 12 O'Clock position which helped slightly the buzz noise was still very loud especially when cold.
So I took the truck to the dealer for the DEF recall and mentioned the buzz vibration at the firewall. According to my paper work as per phone call with GM the tech wrapped the hoses with insulating tape but that did not help at all. After the second phone call to GM they advised him to zip tie the hoses together and raise them. Well the noise is gone completely gone. Not even a hint of the buzz cold or hot. I attached a pic for those who want to save them self a trip to the dealer In the pic, there are 4 zip ties.

So I assume the heater core outlets are rubbing because the holes in the firewall are too small and tying the two hoses together "centers" the outlets.

Thanks for posting this. It finally cured my buzzing noise! The hose rotation only fixed about half of it. I plan to wrap both hoses with a slit piece of radiator hose and then tie-wrap them together and up to avoid any issues.

Also is this only an LML issue? I have a little vibration at the firewall and it would be great to make it go away on my LMM.

I just did mine by wrapping some foam copper pipe insulation around them before I tied them together. That appeared to protect them well.
Noise is gone!!

i would think if the zip ties are tight, they wont wear thru the hoses. ive seen plastic and fabic fuel lines zip tied together and no problems 500k later (class 8 trucks tho
 )

Is this vibration at idle? And does GM officially call this a fix?
