Perhaps if you put in 4hi and turn slowly from left to right you would surely hear a bad front cv joint. Noises can be deceiving when intermittent and could be something else. Slow speed and only hear when turning could be a cv.....
I went to an open parking lot and did several slow figure eights with and without 4hi active, forward and in reverse.. I could not replicate the noise (crunch, screech or rattle). No other noise/sounds were present either. Switching the truck into and out 4WD sounds normal.

......check your hub bearings too. Just spin the tire look for wobble and can grab tire at 8and 2oclock, 10n4 o'clock etc while elevated and see if there is play? This helps with slack in the rack if doing 9/3 o'clock sometimes the racks moves on ya.
In the garage I jacked up the driver side and grabbed the tire at 8/2, 10/4, 12/6, 9/3, etc and there was no play or wobble present. I did the same thing for the passenger side and there also was no play/wobble present.
I spun the driver side tire it and seemed to spin smooth and without a large amount of effort and did not make any noise. When I spun the passenger side tire it seemed to me that there was more effort needed to spin the tire and after a few rotations it felt like there was an increase in resistant turning. Also there seems to be a slight and faint screech when the tire was turning. I couldn't tell exactly where it coming from.

Check the disconnect. That's the side it is on and maybe it has worn and started having enough slop for the CV to rub against the housing at certain angles. There should be almost no wiggle in the CV where it goes into the disconnect.
When mine got worn the CV could wiggle a fair bit.
While the passenger side tire was jacked up I grabbed a hold of the CV shaft/axle (proper name?) between the two rubber boots and also between the rubber boot and the engine side and I did not feel any movement/wiggle.

I just had the same issue, it ended up being the rear u-joint.
I looked at both u joints on the rear drive shaft and both did not have any obvious visual signs of problems. There was no movement (up/down and left/right) when I spun the drive shaft. They did not move when I pulled and pushed on the drive shaft.
Going back to the passenger side tire, is the increase in resistant when spinning it a normal thing because of the disconnect? Is the slight screech a sign of anything?
