What weight oils do you guys run in your diffs and how much? I've gotthe the dana 60 up front and the 80 in the rear. I'm thinking about restacking the plates in the rear to make it more solid than the limited slip comes from the factory and figure I'll change both the front and the rear fluid at the same time. Thanks.

 

75-90, get two gallons and some friction modifyer for the rear.

 

So is the friction modifier supposed to stiffen or loosen the rear end?

 

it is for the clutches in the axel that give you the limited slip feature. without it the LSD doesnt work that well.

 

DAMN you just reminded me that I never threw that stuff in when I did my diff cover. I found out after I did the cover that I was supposed to add it, and I've been meaning to toss it in, but I forgot. Thanks for the reminder.
