Hello. Welcome to Just Answer. Please allow me to assist you. Without feeling the or hearing the noise on a road test, it is difficult to be exact here. However, experience is usually one of the following things:

Tooth broken off of the front ring gear or pinion gear

Front Rzeppa joints or U-joints worn or faulty

Front driveshaft u-joints worn or faulty

Loose front driveshaft yoke.

The thing to do here is raise it up on a rack, have someone start it up, put it in gear and turn the wheel. From underneath, one can listen for the noise using mechanic's stethoscope.. The best thing to do, though, it find a shop that has an electronic stethoscope. This is where transducers attache to different suspected noice areas. The vehicle is then road tested and the individual transducers are listened to via a set of headphones. A proper diagnosis here is the best path to a repair. You could conceivable put a new rear end into this vehicle and not fix it cause a j-joint was bad.
