LSD - Differential Oil - How Much?

[bhmsupra]

I have a low mile LSD and am doing some driveline mods... clutch, shifter etc... etc..

I have narrowed my search (using the search function - YES) down to Redline 75W90 or Royal Purple 80W90.

I can't seem to find how many ounces it takes to change the Diff Oil.
How Much?

1.4qts or just fill until it comes out of the fill plug!

Don't forget the friction modifier. [edit] nvm, its included in either. ::dunce::

Both Red Line and Royal Purple have the friction modifier in the formulation.

I would remove the fill plug 1st before I drained it

Wow, good call. I thought for sure it was still separate, but you're right. It tricked me before that they sell the modifier separate. Just assumed it wasn't already mixed in. What an ass I am for assuming that.

so just incase the the fill plug strips you dont drain the fluid!(same with manual trans)

Manual trans you can get away with it as you can fill through the shifter. You're pretty screwed if the diff does it unless you want to try the breather...
