    My son burned up his rear differential in his 2005 because this vent became clogged.He traded it in for a 2013 so, I'm glad I joined this forum and came across this post.Thank You very much as this will probably save me $ in the future Very helpful!

    Yes, much harder to clog it up if it is up inside the storage compartment and not down in the mud!

    What size are the hose claps for this?

    I just ordered
    90404-51026
    90930-03136

    I am hoping I don't have to order 90404-51319 instead.

    On the opening post, I took a photo of the parts bag, so nobody would get the wrong number...

    [​IMG]

    On the first page of this thread is a photo of all the parts I bought, including a package of hose clamps... ones that will fit 1/2" to 1" diameter hoses... here's a close up of the end, in the compartment:

    I finished the thread and this is as good a reason for a timely bump as anything.

    The Trail-Gear Creeper Breather addresses the second point ^^^ by collapsing as needed. As long as the bellows remains flexible, airtight, and has sufficient volume, it'll work fine. I'd have to have some proof of steam issues before intentionally damaging a sealed bellows. My main concern with this part is the life span of the rubber. Fuel hose is cheap and lasts a very long time.

    [​IMG]

    The T-G part seems like a good solution, but I'm going with the hose. I ordered the parts from David's OP and should have them installed soon. I'll be crossing the Fremont river in a few weeks, and don't want to worry about water contamination.

    Did anyone ever get confirmation on whether or not the e-locker breather needs to be moved as well? It might have been in the 17 pages, but I easily could have missed it. Just waiting on the parts to do this mod next weekend.

    Did this mod just now. For those wondering like I did, the stock breather threading is the same length as the new union you are replacing it with. It can be tightened all the way down to the differential housing. I was wondering why I saw about 1/4 of the threads on the earlier pics, thinking that it was longer and intruding into the gear area. It's not. +1 Rep for OP!

    Did I do something right?!! LOL

    Thank you! You will also note that I wrapped teflon tape on the threads so it would seal without over-tightening and risk of snapping it off!:cool:

    Completed using David K's part numbers from OP. I ran the hose between the bed structure and zip tied it to the fuel filler tube. No need for the extension for the Fremont last week (5"), but it's good to know it's done.

    Thanks again, David. :wave:

    Just finished this mod, routed my breather through my bed cubby. The actual replacement breather valve I got doesn't have much articulation in the little silver cap over the valve, unlike the stock one from the axle, which moves around a lot. There is not a seal or anything, and it will freely spin, but there is not much of a gap. Anything to be concerned about? first time doing a breather relocation with this type of valve. Thanks

    yes
    If you blow through the original part from the axle, you'll see that the movement is actually the valve at work. Push it in, and the air flow is stopped. The new part doesn't act as a valve, so there's no movement.

    That is the whole point of doing this mod... to put a real breather on the end of a tube, above any deep water line.

    The thing that is on the differential from the factory is a one way VENT... It has a spring loaded seal that takes a pressure build-up in the diff. to push against the little spring, and let gasses vent to atmosphere.

    A BREATHER allows venting AND vacuum breaking! That's the key, to break a vacuum created inside the diff., when you cross a stream... The sudden cooling of a hot differential makes the outside air/ muddy water want to suck INTO the differential, passing the rubber axle seals.

    Yes, it happens... either how I explained or or another way, the differential oil gets contaminated.

    Why does Toyota put a remote breather on the front differential, but not on the rear? Specially on OFF ROAD or 4WD Tacomas...??!!

    This mod put the same breather Toyota has on our front differentials, on the rear... and up high in the bed compartment or the gas fill bay, etc.

    Didn't I cover all this in the first page of this thread? No problem, I like talking about my Tacoma... Hope that explains it, but don't hold back if you have questions!

    Hey David, the two breathers that are right next to the battery on an '09 off-road are the Transmission and Front Diff breathers? Or are they something else...

    I'm try to find ALL the breathers on the truck similar to this:

    http://www.tacomaworld.com/forum/off-roading-trails/15093-scuba-mod-relocating-front-rear-diff-tranny-transfer-case-e-locker-breather.html

    But I think two of them are already relocated. Either way, I am running all of them into these instead:

    Specter Breather

    Then I will partially cover those to protect from splash off the fan if it catches water.

    Does that sound sane?


    EDIT: I am running all of them to the driver side front up to a custom bracket I made. Will post pics if this all works out.

    Yes, front diff breather is one of the two by the battery... and your breather choice looks good to me!

    What's the other one? :confused:

    I'm going to start it this Friday since I am off. Hopefully, everything turns out nice.
