Dry bearing noise in rear end
My "new to me" 2002 Laredo has a noise coming from somewhere in the rear that sounds like a dry rubbing.
I especially hear it at low speeds, when decelerating. At other times, it is still there but not quite as loud. When slowing down, it's not a steady grind, but it kind of pulses, like something is warped. It's not a howl, more like I'm dragging a cardboard box underneath the Jeep. At other times, it is still there but not quite as loud.
I was having some grabbing in the rear when turning, so I replaced the diff fluid and added the Mopar additive. That seems to have cured the grabbing, but not the noise. I didn't notice it when I bought it and have put about 1k miles on it since then and the noise seems to be getting louder. The rear wheels don't seem to have any play like with a bad wheel bearing.

Where do I start? Brakes dragging? Wheel bearings? Carrier/pinion bearings?
I talked to Kolak a few days ago about tires and lift, (which I plan on doing in the next couple of weeks). I am going with the IRO 3" and some taller tires to get away from the soccer mom look. I would like to replace whatever is making the noise while I have it all apart for the lift. Plus I want to fix it before I put more stress on it with tires and lift and seriously damage expensive parts.
