    Ok, so I have 90,000 on my '12 dcsb. I use it for a work truck in the oil filed, lots of mud and some pretty deep mud holes sometimes. There is definately mud all over the diff. I'm getting a feeling I should check the oil and change then do the mod. It's not a matter of cost its shutting down long enough to do it.

    Change the diff fluid and look and see if water is in the old fluid.
    If so then you NEED to do the mod. If no water is in the fluid then you might think about it as a preventive measure.
    BTW, the diff fluid should be changed every 30,000 miles.

    You can't hurt anything by doing it.

    I just completed this mod last night. Ordered the oem breather plugs from the dealer and bought 6ft of pressure hose and worm clamps from Lowe's. I routed my breather up the wheel well and into the bed side cubby.

    ^That would work as well. I bought a new one because mine was corroded.

    Lol, yeah, shipping to Hawaii is almost always more than the order itself.

    OMG... did you (and so many who also replied) ever read any of the posts on why the stock breather doesn't work!!!???

    1) It is not a breather, but a vent port for gasses. It doesn't let air back in the differential to break the vacuum created inside. The vacuum is what draws in water when you ford deep streams or pools.

    2) We use the true breather that Toyota puts on the front differential... and it is also mounted up high to keep water out, and let clean air in that breaks any vacuum.
