there are a few things that can make this noise.
The internal gears of the diff. The spider gears could be whornout or chiped.
The bottom plate hitting something when breaking. This could also be the exaust hitting something.
The brake plates. When the center gets whorn out.
The driveshaft from de center to the rear ore the front could have to much play on the outdrive cups.
The bearing could be at the end of there lifetime.
If its not one of these things I am in the blind and whould not know where to look.
Let me know when U figgured out what it is.
