Rear gear/rear noise

I don't know alot about the KJ but my girl has one and I have a question about the rear end.... It's been making a noise and seems kinda "grabby" Do they come with a posi unit ? If so I'm assuming It needs the posi lube ???

You may have Trac Lock limited slip diff. Can't tell from your post, would need more info but check this link out:

If you still have a window sticker or build sheet it should say. If so then yes you need friction modifier.
