High-Pitch Whine

I have an 07 Z71 (new body style) which has developed a high-pitch whine. At first I thought it might be the tires, but that was ruled out after I installed a new set.

Sounds like either the xfer case or rear diff, but could be the tranny. Just wondering if this was a known problem and if anyone has experience that here.

Thanks!

What causes it? I've never towed anything heavier than a 43" cut lawnmower on a 10 foot trailer. Never had it off-road. Glitch from the factory?
