I would doubt that you need to do anything, except put a drain pan underneath the jeep when you park at home !1
My '08 JKU Rubi leaked for the first 6 months, out of the FRONT breather tube and it is just "OVER" fill diff oil, that expands under-- use HEAT--
I suppose you could check your diff. drain plug and DRAW several OZ, just to slow it down !!
