I finally spent some time in 4-low with my LX this weekend. The transfer case is quite loud in that mode. It sounds like a turbine I guess that gets louder or softer depending on how fast I'm going. Just wondering if this is normal?
Is your transfer case loud in 4-low?

I can definitely hear it in 4lo.
But “loud” is a very subjective term.
Perhaps you can record the sound in a short video clip and post a link to it on YouTube...

I guess "loud" meaning I can certainly hear it where in 4-high, I don't hear anything. It doesn't feel like anything is wrong, so I'll just assume it's the normal gear whine as @Chocolate stated.
Straight cut gears whine. It's also true in some vehicles when driving in reverse.

The forward gears in 4Hi are helical so they should be quiet. They are straight-cut in 4Lo. If it's just gear whine and not growling or grinding it's normal for any truck

All of the 3 200s I've owned including the 2 I currently have whine pretty loudly in 4 low at speeds of ~15 mph or more. Obviously it's not a great idea to be in 4 low for extended periods of time above those speeds, but it's necessary on a lot trails with a little distance between obstacles. It's louder than I prefer, and I thought about seeing if a higher quality fluid in the tcase might quiet it down a little.
That is normal. 4 lo has straight cut gears. The same was true in my ‘03 4Runner.

My 100 series did the same thing.
Plus...you could FERL IT since the transfer case had a manual shifter (wish the 200 had a manual 4hi/4lo shifter, actually...ehich would do away with the weird disabling effect other error codes can have on shifting between hi/Lo...

I was concerned because I didn't recall my 80 having gear whine like that in 4 low.
