How bad is rear end grind on decel?

Ok first off, it's NOT my transfer case, definitely the rear end. The rear end overall sounds noisy and kinda rough while I'm driving and on decel makes a light grind. I've done some searching and I've read other people having a death whine type of noise but not grinding. I don't hear it at all while accelerating. Any input? I had STM flush all of my fluids about a year ago but haven't touched it since. I basically just want to make sure it's not going to lock up or something and leave me stranded. Again, it's not super loud but I definitely hear it.

I've been around evo's for a while now and have never heard a rear end problem, that's why it's raising a red flag. Don't know if it's normal or serious.

I'd suggest pulling the drain plug and seeing if you find chunk style metal.

I've seen a pic of an exploded version of the rear and a while back and it looked basically like a bunch of clutch disks and a ring/pinion, is it normal to get a chattering/grinding noise on decel from the plates rubbing together slightly or is any noise like that a bad thing? Any other input anyone??? And I'll pull the plug tonight and take a look, just have to get new fluid first.
