    I've read at least a half dozen write ups on the differential breather mod. I have a couple questions, though.

    1. Can a differential breather go bad?
    2. I've seen a couple write ups that suggested using a fuel filter on the extension as opposed to the breather. Has anyone gone this route? If you did, what kind of filter did you use and where did you get it?

    I have used fuel filters before. Just get one that fits the hose you are useing as the creather extension. Personally, I think a filter is better as it prevents any crap from getting into the gears. A regular breather is simmilar to a flapper valve.

    Thanks Chris. I read that using a filter instead of the breather allows the differential to "breathe" easier preventing any pressure which in turn can help prevent the oil seals from leaking.

    Would you leave this filter open ended or put some sort of cover on it. I would imagine it would be left open ended.

    x2! I need to replace both outer axle seals (they're leaking), so I figured the breather mod will help prevent me from having to do it again anytime soon. I have the seals and 1/2 the stuff for the breather extension. I just have to get to the dealership for the union fitting.

    I extended my rear diff but decided against my tranny and t-case.

    I dunno if it is the same for the tranny and transfer case, but for the rear breather, you'll need:

    8ft 1/4" rubber hose
    2 small hose clamps
    1 "union" - Toyota part# 9040451026
    original breather or substitute a fuel filter that will fit the hose

    I believe the front diff is already extended up to th fender under the hood.

    i know a lot of guys tend to use that yellow coiled air hose as it will flex a bit and not pop when your suspension flexes out

    i think i'll stick to the regular fuel line myself, you can make it long enough, and its pretty tough and abrasion resistant already, plus its probably a bit cheaper.
