Noises are hard to tell over the internet unless you upload a video of the noise, I know that sometimes when the axle bearings go out it can cause a grinding noise. I would check to make sure it is not the e brake shoes hitting the rear rotor, I have seen that as well. Here are some exploded views of the brakes and axle bearing in the diagrams below to help us see what's going on. This video can help as well:
