Can anyone explain how the rear ball diff works on the optima mid?
I've found the gear and it just occured to me that the gear and belt sprocket are right next to each other.
So how does the thrust balls touch both end friction plates???
Or am I being dumb?
This is what I've found for my OMCS.

Can I make a rear diff with this and a W0107 front ball diff set?
