    I took the spare tire out of my truck the other day and noticed that my rear diff was oily. There was dirt and gime on the diff plate and fresh oil puddled/hanging on the bottom of the diff. I asked my brother why and he said that the oil must be getting really hot and is pushing out of the seals. I drive 40 highway miles a day and have 285/75/r16. Do any of you guys have answer for this?

    Ask your brother how the oil is pushed past the seal on a vented diff.

    Get a light and get under there and find out where it is coming from
    Drain plug
    third member gasket
    Pinion seal
    Do you have a locker?

    If it is not obvious get some parts/brake cleaner and a rag and clean it up and then check again after a day or so.
