Grind noise during quick turn

I was at a stop today, and had to do a quick left turn to cross the road and beat traffic. As I did the quick acceleration with the wheel already turned, I heard a griding noise - kind of like the 4x4 was catching, I think. I verified it was in 2hi.

It's a 2001 4x4 with 108k miles.

Any idea?
Thanks

CV joint is going or the 4x4 was partially engagged.

Also could just be the rotor grinding against the dust shields which commonly happens.
