rear differential breather relocate - 3rd gen 4runner version - **pictures**

Today I relocated the rear differential breather. These parts were courtesy of @Unchained 5150 . Rick, you will always be a part of my 4runner build buddy.

The parts needed were:

Toyota parts:

Union part:

$7 90404-51319 Toyota Genuine Parts - Union (90404-51319)

90404-51319

Breather:

$7 90930-03136 Toyota Breather Plug - 90930-03136

90930-03136

One hose clamp

Teflon tape

about 6 feet of transmission hose. I went to autozone and asked them to provide some hose that fit the Toyota breather fittings. Took the fittings with me so they could give me their best fitting hose.

Here are the parts pictured:





Made sure to Teflon the threads on the union part. I fitted the parts into the hose to stretch it out and allow ease of installation once I was under the 4runner.



On the driver's side rear wheel well, I located the fuel filler neck dust cover. I removed the lower clip that holds the fuel filler neck dust cover:





Next I popped open the fuel gas door.
This allowed me to grab a knife and cut a small hole small enough in the rubber surround to hold the breather fitting but large enough to allow me to fish the hose thru.



I reached behind the fuel filler neck dust cover and pulled the hose thru



The hole I made in the rubber surround of the fueling port is tight enough to hold the hose in. I didn't clamp this end since the hose was a very tight fit. I had to dab the fitting with some light oil to get it in the hose.



I then fished the hose to follow the fuel lines and what not..



I then located the existing breather:



Removed it and installed the new union part. Make sure to Teflon!



I went ahead and attached the hose and clamped this end.



I allowed enough slack to make sure there is enough hose to reach during articulation by matching the length of my extended brake lines.

 

@willhaman21 is alive!

 

@ramonortiz55 and I probably passed my Econ test today! Woohoo! Now just waiting for Toyota to call and tell me that my parts are in so I can get my breather mod done this afternoon

 

probably?

 

Wellllll, most likely lol. I could of nailed it, or I could have failed it...

 

come on haman, get it together lol

 

I'm not too worried about this semester. I pulled a 3.93 last semester, so I can coast a bit! Taking differential equations, physics 3, physics lab 2, dynamics, thermodynamics, economics, and modelling with Solidworks.

 

differential equations?...meh

 

Yeah not my favorite haha, but gonna be my last calculus class so that's awesome. Also, we get an 8x11 cheat sheet for each test! Hallelujah lol.

 

I seriously need to do this. My oem breather kinda annihilated itself when I took @snivilous to escalante, UT last august.

I just did the barracks trail a few weeks ago near Zion NP and there were 2' deep water crossings, changed my diff oil after and it was a chocolate caramel milkshake

I don't think this is helping the life of my elocker either...

 

Get'er done Miles, it's pretty damn simple honestly, took maybe 20 minutes. The rubber boot around the gas filler nozzle is the hardest part.

 

whatchu doing in here...

 

I'm here from time to time, not like you full timers with nothing better to do
