I just bought Eaton and Superior 31 axles and this Saturday me and my friend will swap them up
So question is will stock(OEM) differential berings works with Eaton diff,
2ns question is what kinda differential oil you guys use with Eaton
and 3rd question is how much backlash you guys did

I have no idea on any of your questions, sorry. I took it to Hoss's Gear Shop out near Latrobe and had it done there. I know Eaton recommends a SPECIFIC rear end fluid but I can't remember right now what it is.
