Help! Two weird noises 2017 Tahoe LT 4x4 5.3L

[TahoeFL2017]

Ok guys help me figure out two noises, before I take this to the shop

On takeoff from a dead stop, after the truck has fully "settled" after stopping, there's a light "thud" from the rear, that is barely noticeable, but definitely there, maybe a u-joint?

Then on right turn there is a pop noise, very subtle, but you can hear it more on right turns, and not every time

These don't seem serious, but I'm a fanatic on keeping this truck maintained, as I want to get 300k miles out of it.

Any ideas?

Is there a TSB for frame mounts, could that be it?

Take the truck to a trusted local repair shop and put it on a lift.

First noise could be a U-joint, or possibly a wearing issue in the rear differential

Second noise could be a failing CV joint
