But then again, I would check ball joints, steering links, sway bar connections, and shock attachments, just to make sure it is not a weird alignment thing.
That'll only check your outer CVs. Inner CVs are only mildly stressed in turns. They are stressed in situations of suspension flex.

Cloud, I'm thinking bearings as well. The easy test for this is to jack up the front and jiggle the whole wheel assembly top to bottom. If you get any play, then the bearing pre-load needs to be adjusted (or bearing replacemnet).

I always start with the simple stuff & work towards the harder. Since you've already checked the brakes & CVs (I assume all 4 & not just the outers), pump some grease in your U-Joints, check fluid levels in the transfer case, tranny, front & rear differentials. Have you had an alignment done recently? If not, then do so (that shouldn't make a grinding sound but if caster is way off, then you may have a tire touching something in a turn (ask me how I know)).
