    What are the part numbers I need to order for the 3rd gen to do this mod?

    I've crossed water where the axle is submerged a number of times and am now worried since I haven't done this yet.

    Should my rear diff be opened up now?

    Is this all I need? Do I just use the existing breather with this setup above?


    Also found this on another thread. He mentioned a 2-way breather. Is that right?

    Also, I saw this from @DrFunker, can you confirm the part numbers needed to complete this kit?

    The parts I listed are from a Land Cruiser and have 1/4" barbs. The breather is a two-way.
    Yes, you want a two-way.
    Re-loacting is only half of it; eliminating vacuum is the the other.
    When a hot differential hits cold water, it creates a vacuum.
    Water contamination occurs through the axle seals.
    Relocating a one-way doesn't eliminate vacuum.

    It's got a cop motor, a 440-cubic-inch plant. It's got cop tires, cop suspension, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.
    Is the factory breather on the front 2 way?
