I'm thinking if the speedo is registering steady and varies with engine speed as you depress the accelerator, then something has failed behind the point where the speedo drive gear is located on the splined end of driveshaft. I'm thinking the driveshaft to pinion coupling, an axle shaft, or an axle key has failed. If it's not an axle key that sheared, then most likely that rear will need to come out.
