How do I take apart the T2 S5 Diff?
 

I'm trying to see what kind of diff I have (some sort of locking 1.5 or 2 way) I took out all the bolts and I know the cover is siliconed. I tried separating it, but no luck.. What am I doing wrong ?

you have the bolts out, are the axles out?

Check out that thread.

Haha you probably forgot to take out the halfshafts

If you did that already, whack it with a hammer (no, not a big steel one)

the diff is completely out, it looks like this
