Hi,

Does anyone know what kind of gear oil or diff fluid goes in the rear diff? Im having trouble finding this information online.

I have a 2012 4WD Avalanche.
 
I see no mention of a limited slip lubricate for the rear end on page 11-12 of the 2012 Chevrolet Avalanche owner's manual.

Am I wrong in understanding the rear ends in these trucks are mechanical centrifugal locking and not clutch limited slips, like in the old days?

I know the G80 in my 2003 Avalanche is mechanical and not clutch based and therefore needs no friction modifier.

I'm sure someone will correct me, if I am wrong.

:unsure:
