GRINDING NOISE FROM REAR!

Had the same problem, couldnt narrow it down. Had the entie rear end replaced. It went away. But that was under warranty so didnt care about the cost. Maybe a wheel bearing / axle bearing?

+1 Agreed.

It's kind of tricky. You have to pull all of the brake hardware off, unbolt the brackets, drain the differential and remove the cover, push axles in and remove c-clips, remove axles, then remove bearings with a slide hammer and rear axle bearing removal tool. If you're brave, you can tap the bearings in like I did with a big 4x4 hub nut socket and a rubber mallot, or get one of those bearing/race installer kits. You'll know if it's a bearing, if you raise up the back of the car, and the tire has alot of movement front to back and up and down. I believe it might be something else though. Are you lowered at all, and do you have steeper gears installed?
