What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Yeah, I had a squeaking on start up in temps near or below zero so I swapped out both the pulley and the tensioner.
Mine wasn't a chirp but it was a constant squeak until it warmed up.

I don't know about newer Yukons... but I, ( '05 Yukon ), changed my belt tension-er, that's way down below, next to the A/C .compressor....
Since, it must take a beating.

Installed the rear DJM end links today. Seems to corner a bit better. I still have a bit of tire rub, driver side rear, on hard bumps. It’s the tire rubbing on the inner fender liner. They’re 275/55-20’s so there’s a lot of tire. I might have to trim; I did the heat and massage trick already.

Newer engines have the tensioner up near the top of the engine and a stupid stretch belt for the AC compressor, only, way down low.

I was scared about that AC belt, after reading other posts, but I've now removed and installed one with my bare hands and a ratchet on the crank bolt. It's not that bad in reality.

Installed mud flaps and changed the serpentine belt on my ‘16 Yukon, figured that would cure the problem “chirp” at startup. Whether it’s cold or hot, it does it. Anybody have an idea as to what it could be? Thanks.
+ I walnut blasted my intake valves about 2-3 weeks ago, would that have anything to do with the chirp?

Rare, but check your starter bolts, and maybe even the bolts on your torque converter

The one I installed was about 2 inches shorter in overall length than the one I took off.
It was a pain to get onto the crank pulley, without a stretch belt tool it wouldn't have worked.
