You need to immediately check the differential for fluid. Problem is if it is low there is usually a reason (leak) and by the time you hear it it might be too late (sorry). You can also get water in rear end from vent tube being broken or removed, that will smoke the bearings also and make it howl.
If you are lucky it might be the rear universal joint, it could be dry and going bad.
I would pull the rear end cover and look at things. If it looks good and had oil clean the gasket surface, put some silicone sealer on it and button it up... move to the U joint. Unless it is wasted it will be hard to determine if it is bad. I usually take the shaft off the rear end and manipulate the u-joint by hand so I can feel the grinding.
Sorry if it is bad news.
