    I got an 06 Tacoma trd off road 4.0
    it has 19k miles on them and I want to replace the front and rear diffs on this.
    what weight do I need for front and rear?
    also do I need limited slip additive? its got the rear locker.
    thanks in advance.

    I've heard not to mix LSD and other drugs so I feel like an additive is probably a bad idea... :p

    Haha sorry I'm no help. Couldn't resist

    I hear a little mix reviews. so mine isn't a "sport" so I don't need the additive.

    I'd run the recommended GL rating (5?) in the recommended viscosity (75w90?) but in an OTC synthetic, like Mobil 1, that can be found everywhere and often on sale.

    If you use it hard, just change the lube at 1/2 the suggested intervals. Or if you flood it with water of course.

    Loosely related, but thought I'd share for the laughs. My buddy was stuck like this in his 4runner for about an hour. I recommended he change his diff fluid, so he did. He said it was pretty much mud coming out. He soon after did the rear diff breather mod.

    Covered in stickers and chrome stick-ons for extra horse torques and foot powers. Icon sticker gets me tons of travel, dozens of milimeters.
    Offroad package does not need slip additive.
