I have a sticker in my glove box that tells me the build codes. Most of it is faded away.

I do in fact have the dana 80. It says 10.1 pints of gear oil, and 10 oz of friction modifier. What brand of friction modiier should i get? Im geting the valvoline 80w-90

Get it from the dealer that way you know you have the right stuff :c:

What fireman said. Mopar additive. And before you it up what I like to do is flush it out persay with a little extra fluid.

Gotta see what the dealer will charge for it.. Probably an arm and a leg for 10 oz lol :argh:

Cant get a straight answer from anyone i talk to. Now apparantly they say valvoline 80w-90 in the white bottle which is 100% non synthetic also has friction modifier. Valvoline told me it has 4 oz per qt, which will mean ill have 20 oz of friction modifier in my differential when i only need 10 oz. i think im on a journey to wasting all kinds of money on crap i dont need. Dodge dealership still says ad mopar friction modifier, but wont that make it way too much? :argh:

Im about to say to hell with it and leave the dirty oil in there
