I have a very harsh grinding type noise coming from the rear when I go over certain bumps while driving slowly.

Yep, this happens when the E brake shoes need to be replaced you will need new brake rotors as well.

Here is video of the job being done so you can get the work done:

So, you don’t think it has anything to do with the differential? Is there any danger with driving it like it is?

Yes, I would not drive it with that sound, it could cause the wheel to lock up, the noise will happen whether you are using the brake or not because the E brake shoes are drugging on the inside of the rotor (drum part) please check out the video I sent you so you can see what I am talking about.
