I'm not an expert so take this with a grain of salt...
Even if you disconnected the rear drive shaft the rear axles will still spin and the differential will too. Some guys have heard strange noises for quite a while and finally realized the differential was the source. Still, if it was me, I would have it towed to avoid further damage or to avoid complete failure that left me in the middle of the road.
