    Dont recall what size the nut is, sorry. Buy both to CYA. As for the gear oil, AZ heat and all, go for the thicker stuff. Which reminds me, I need to change mine soon :)

    I have no idea on the nut - I run 90W-140 in my diffs for the heat, and thanks for the reminder - I need to change mine too!

    I'm so poor I can't even pay attention [​IMG]

    Hey Impex i'm pretty sure that nut is 1 1/8th. I've always just run 80 90 wt gear oil
