I have a 2011 Tahoe LT with roughly 50k miles. It's been perfectly maintained, even recently changing all axle fluids. I'm now noticing a mild whining sound only at light acceleration when I am making a hard turn. I've checked the fluid in the rear and it's still full of very clear axle fluid. Again it only does it when turning, as light acceleration in either drive or reverse will not replicate the noise. Has anyone else experienced such a thing? Appreciate any and all help.

I'd have somebody check the rear diff and do it quick. When that happened to us it required a full rebuild when we left it too long.
