Hey guys, just about finished on my rebuild, one of the last things I’m going to do is change out the differential oil in the front and back. Does anyone know what kind of gear oil should go in the front and what kind in the back?

75w90 or 80w90 will work, use one with limited slip additive in it then you don't need to worry if you have LS or not. Newer vehicles will use 75w140, this can also be used.
