Diff oil

How much oil needs to go in the front diff and rear diff?
Also the manual say to add 4oz of LSD additive, I got some and it seems to be like a paste, is that just squeezed into the rear end or does it need to be applied to the gears on the diff?

If your truck is perfectly level when you change the oil it will hold around 2.25 in the back end. Check for a drain plug, my 12 has one.

what size is the drain plug? I am ready to do mine, but haven't found the right size tool for it.
thanks.

Thanks for the input.
Now, any tips or tricks for doing the front?
