Do you mind if I piggyback off your thread? I have a 2018 yukon and I experienced a similar "drag" as you have called it in 4WD and only in 4WD. Other conditions are only during tight turns like when in a parking lot. I was in 4WD because we had received a lot of snow and I forgot to put it back into auto. At first I thought maybe there was snow built up in the fenders and that was preventing me from turning the steering wheel all the way. There was snow built up and I removed it but I still got that same drag and resistance with the wheels turned. I saw some comments about being on pavement or cement. Should 4WD be avoided on pavement or could there be a more serious problem? Thanks

I would check the allignement, expecially the caster and camber.
I have an Escalade with permanent AWD and I had the problem as well, that if I sharply turn the wheels, that I feel a tension and rubbing wheels.
I make my own allignement tool and found out that there were the original retainers from production, so that no one in 150000 miles changed caster or camber and both where fully out of specification.
I did the allignement and my car now drive much better and turn in sharp curves without any tension.
For understanding: Especially if the caster on the wheels is different and not correct, then the angle of the wheels to each other, does not change correctly, when the wheels are turned. That leeds into tension. If everything is adjusted correctly, the wheel on the inside of the curve is steered further than the wheel on the outside of the curve, because this has to make a smaller circle.
Besides the fact, that the four wheel drive of the Tahoe is not designed to be used permanently on dry roads. This increases fuel consumption and wear.
