I'm really confused now because I don't know if my ring and pinion are bad or if I set up it not good.

don't get me wrong but it sounds like you'd be better off having a specialist take a look at it. Assembling a diff properly takes skill and experience.

Yeah I know but I like to learn by myself and I assume the mistake.
That's why I ask a lot of informations.
I'm doing my own experience.

you could still ask someone to supervise you or be prepared to spend quite a bit more money than needed.

At this time I just changed the bearings because they were worn. So I didn't spend a lot of money but I'm almost sure that it's the ring because it's the only thing that I've forgot to check.
My setup is good.

What do you mean by that:
If the gears appear to be
in good condition, you could try adjusting the contact patch, or just put
up with the noise, and hope that it settles after a while. ?????

I should set up the ring much closer of the pinion ?
With the same method showed in the factory service manual ?

When you dismantled the diff there should have been a wear pattern
(contact patch) visible on the crownwheel teeth. Providing the contact
patch was correctly placed on the face of the tooth, you should have
tried to put the diff back together with the contact patch in the same
position. The procedure is in the FSM, and some nice pictures here...

Did you adjust the contact patch during final assembly of the diff ?
