I can't tell if this is coming from the front end or the rear end, but when I turn corners I hear a whine/groan coming from somewhere.

I know the power steering pump squaks a little, but it seems to be coming from the rear end. I'm just not sure.

Any thoughts?

Not sure about this, I have a 2 wheel drive Dakota but I have read that on the 4 wheel drive a noise when turning like that can be caused by a bad wheel bearing/hub assembly. I would say check that first. Maybe drive it with a passenger in the truck with you and roll down the windows, turn some corners and see if you can identify the source/area of the noise.

Just my 2 cents.
