    Just ordered built front diff and rear gear kit (4.56 gears) from east coast gears. They recommend using Lucas 80/140 (dino) on front /Rear and transfer case. I have always used mobil 1 syntho 75/90. They claim that syntho is not as good as dino due to lack of cushion. Can anyone verify this. What has everyone been using on their rear/front diff and transfercase

    80/140 seems amazingly thick, but if that is what the manufacturer recommends, I'd go with it.
