    I was told this once but kinda forgot. how i remeber it was they(infamous they) said the transfer and trans was routed up behind th eengine by the firewall but it was low and a pita to get to. the front dif was routed near the battery i believe they said..i'm going to take a look at my posts and see if i can track this down.

    as for keeping the breather by fittings you meant the ones that will link the extension hose right? because if they are already there like in those pics here, then all i should have to do is extend the hose...all i would need is some hose and hoseclamps in my hand i would think? the rear diff however is just sticking out of the houseing so you would obviously need the breather and union.

    edit: found it
    so those 2 are the front diff and ADD. i wonder if the tranny and trans breathers are set up like the rear diff? or are they actually extended a bit.
    i take it now that there is 4 in the front.
    1.front diff
    2.ADD
    3.Tranny
    4.Transfer Case
    Am I wrong? someone teach me
    what the hell is this 3rd one then? he has an 06.

    Diffs that are already relocated should just need additional line if you want to move them further....anything that is still on the diff/case itself is going to need a new union to go in-situ.

    Yeah I noted those breathers on inspection when taking delivery of my '09. I knew one was the front diff, haven't had a chance to look into the others yet (had the truck for a couple busy days before heading right back to the dealer to get the rear leaf TSB out of the way early) and see what they connect to.

    Supposed to get the truck back tomorrow or Sat at the latest, going to spend some time this weekend eyeballing breathers that can/need to be relocated. Will report back when I have some answers.

    Edit: And my name's not Roger :)

    I saw somewhere where a Tacoma owner ran the diff breather line to the rear driver's side storage box in the bed of the truck and bolted the breather fitting near the top of the box to keep the water out. I think you have lots of options in doing this. The bed cubby comes out by pulling the box up and then out. Yes, It is held in place by 3M tape but sits in a groove so the 3M tape is not the only mechanism keeping the pocket from falling out. Hope this helps. :)

    Are those wires coming from the front of your differential for an e-locker? Can you tell I don't have one if I don't even know what it looks like?

    Thanks

    if you have an e-locker, do you also need to extend its breather? does it have one?

    As I understand it, the e-locker is an electronic locking pin that takes the rear diff from "open" to "closed"...the equipment is electronic, and the pin itself is in the diff. No add'l breather req'd.

    Was thinking the exact same thing....you want some bend, flex in that line.

    Doesn't have to be a ton, because the pumpkin is pretty much the axis of side <--> side articulation, but you'd want to allow for at least six inches of travel for the diff.

    It's hard to see in this photo, but off to the left there's a fair amount of slack hose to allow axle travel:

    It's 3/8" ID 5/8" OD high pressure hosing. You can get it at your local hardware/home improvement store. Lowes happened to have stock only in yellow.

    The big advantage is it's almost impossible to kink or collapse, so you can route it through a cutout in the frame like I did to keep the routing clean without having to worry about whether or not it will get shifted and kinked closed during enthusiastic driving.
