Non 4x4 non TRD rear Axle

[Willie]

Folks-
I have a 06 2wd double cab 6cyl auto non-trd.

Can someone tell me how to identify the rear axle in this thing?

I found the axle code (I think) on the door sticker to be A04A
In addition there is a sticker on the rear diff that says: C3 062006 0618

All the online decoders I can find are for 01-04.
I searched the national boards and Google but got tired of reading bullshit.

I am trying to determine the axle, the ratio, and if I have posi.

Thanks

Call the dealer with the VIN#?
