Notorious Has anyone heard this noise before

[Dakota]

I believe it is coming from rear diff can anyone please let me know what they might think it is before I tear into it ??

It’s the rear dogbones floppin around when you let off throttle is what I believe. Nothing to be alarmed about. The fronts are cvds and you won’t get that from them.
Now if you hear crunching while on throttle while driving it, you will have a problem. But, hey, pull the diff anyways and inspect. Maybe add some thicker diff grease and a couple shims to beef it up. Get to know it.

It’s definitely not the dog bones I changed both those out it’s a much different noise .. I think it’s inside the diff I’m just gonna have to tear apart

Yup! Tearing it apart is only way to find out for sure.

I think a few teeth gone on ring gear
Or bearing shot and it's flopping around in there

I second this. I'd be cracking that diff case open and having a look inside.
Let us know the outcome!

Sounds like a coffee grinder!

Coffee???? White with one please

It sounds like it’s the ring gear....I think the clunking would happen at a faster pace if it were the pinion since it rotates faster than the larger ring gear. I think I did the same thing on my front diff but haven’t looked at it yet.
Can you move that one back and forth like you can the center diff?

Can I move the front middle or rear?

This is the issue .. so far lol
Mind you this rig was one day old lol

 

[Mongoose]

I think the ring/pinion mesh needs to be shimmed....or at least it won’t hurt to check it.

You can have that happen to a rig that is 5 minutes old.
