1G 4 bolt rear differential noise

[AWD-Tony]

My rear differential has a noise on decel only at a certain speeds. I have an extra diff that I'm preparing to install. Can anyone tell me if this noise is normal? Again, the one in the video is an extra diff I picked up a while back.

Thanks, Tony!

The noise is normal, they all do it, it gets worse with a twin disc.
