Differential Breather Mod for Dummies (Pics)

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.

 

roger did you look at my edit? weigh in on that please

 

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

 

cool maybe i'll do the same this weekend.

its funny how verbal habits will happen even when youre typing

 

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

 

yep thats what I was looking for. Thanks neubs

 

Yes sir! That is my E-Locker.

Anytime!

 

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.

 

thread revival! dumb ?, are the unioin and braether part #'s the same for a first gen? also did anyone order them from toyotaparts4u.com?

 

A little late but I think the part is the same. Someone please correct me if I am wrong. Here is another link:

Yup it looks like the same part work for 1st generations too. Here is a link:

Post number 9 on the referenced thread notes:

8 feet of 1/4" rubber fuel line
2 small hose clamps
A few nylon wire (zip) ties

 

This will be my next mod...hopefully will complete this weekend.

 

great job,i wished i would have seen this before i did mine...........i mounted mine in the cowl of my evinrude.

 

Just did the mod.

Also changed the dif while I was at it.

 

Do you have any slack on the line? It looks pulled tight. First time off road its going to pull apart or break something

 

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:

 

Did you photoshop the tube to make it yellow and stand out or can you buy it like that anywhere ?

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.
