Rear Diff Breather Mod - Complete!

[lojack323]

I actually did a slight variation on what other folks did. I routed the diff and e-locker breathers up on top of the fuel filler pipe all the way to the area just behind the fuel filler chamber, up at the top of the left rear wheel well. I didn't feel comfortable cutting up the rubber and plastic that is supposed to keep the "outside water" from becoming the "inside water", but I wanted it to be as high as possible. This part of the wheel well is covered by a plastic splash shield, and the area actually seems to be a lot cleaner than under the fuel filler door. It did take some fanagling with a small 12-point socket (I think it was around 10mm) to release the plastic panel clips from behind.

You unclip the splash shield, run the breather tubes up along the filler pipe as high as they will go, secure with zip-ties, then button the splash shield back on.

I like this. Do you recall about how many feet of line you needed?

Any issues now that it's been ~9 months with it there?

Has anyone caught a wiff of the diff fluid inside the vehicle as a result of running the breather up into the jack compartment?

I did, only when I had the recirculating air on though. It seemed to go away after I replaced my cabin filter

I do under specific conditions. 30-50mph under load, more so when going uphill. Elevated when the back windows are down, or if the recirculation is on. It's weird, and I'll likely reroute my lines outside the vehicle at some point. It's not terrible, but noticeable at times for me and the wifey.

I ended up running mine behind the wheel well liner up along the fuel filler pipe.

Now that I’ve crawled under mine and done the diff breather mod, I understand this way better.

Thanks!

:bravo:

PS I bought some heavier duty rhino truck ramps which gave me an extra 7.5” underneath, which I was glad to have . . .

Hey Viking-777 sorry for the late response! I often check this forum but don't always log in.

Yes that was the correct kit for the ARB and also, yes the union was threaded correctly for the TRD Pro Rear Diff. The eLocker doesn't need a union. The factory included a little rubber tube that has it's own plastic union piece a short distance off of the eLocker on the rear axle. I pulled the tubes apart at that plastic union leaving the longer tube going to the factory breather taped shut. The remaining stub coming from the e-Locker I inserted into the larger diameter fuel-line tube. I used a hose clamp, not too tight to keep the tubes from sliding apart. In the picture you can see the blackish, plastic union piece for the eLocker breather just to the right of where the bright light is shining:

I am glad I gound this thread. I will be doing this in the near future, but I will just buy the ARB kit, most of the links on here are bad and since it's a old thread the ARB should work with a 2019, I like how the video I found they ran it up to the engine bay. The kit just makes everything easy and I see I can add lines to it so I can run the others to it. I have no clue what the E locker is and that seems to me a headache.

This is great, thanks for the link to the writeup, this is now towards the top of my mod list!
