I took apart the rear diff and sew that the bevel gear OUTSIDE the diff cup.(Part# 86336) the small one that spins on the larger gear that's on the diff it self. It has frayed edges and looks a lot more messed up then the front one. So I'm assumeing this is the issue cause the diff gears inside function fine. So my question is. Does anyone have an extra one of these. Or a link to just the small bevel gear
