Yupe mine too, but only after a slight lift did the slight grinding start, and it sounds exactly like you are describing. My dad thinks it has something to do with the larger heavier tires/wheels and different tread pattern.

An easy way to check it is to pull all the plugs off of the TOD module under the pass. seat and drive it. You will lose ABS when unplugged so don't panic. What I did to make it easier to live with day to day was to put a TOD disconnect switch wired to a 10 watt resistor to simulate load. There's a good write up for that on here somewhere. You just have to remember to turn the TOD back on in the slick stuff, that short wheelbase can swap ends REAL quick! Another thing to check for driveline noise in the rear is the clutch packs for the LSD. I toasted mine rallycrossing for a few years and had some noise there as well.
Jay and I have talked about this before, and I totally agree with him and this grinding may sound like it is coming from the rear, but actually is occuring because of the lift/change in axle angle, even a slight change.
