Grinding noise when decelerating/engine braking below 20mph
This used to happen occasionally but as of today every time the speedometer crosses 21mph it makes a loud grinding noise all the way down to 0. It doesn't matter what gear I'm in (SST), if I'm in neutral, or if I'm on the brakes or engine braking/coasting. There is no grinding when accelerating at any speed or decelerating above 20mph.

Other than this loud grinding the car drives perfect, shifts perfect, and makes no other noises. I'm stumped by this because some threads lead to it being the t-case but they don't have the noise at a specific speed range.

Can you feel it in the pedal or shifters?
Feels like transfer case based on how you describe it is there any way to hook up a mic closer to that to see if it is the noise you're hearing? Those are about $4500 new which sucks, but you could probably find a used one as well there are a lot of retired MR's around with more than likely pristine transfer cases.
