- Today we tackle a differential breather relocation on the 2007 4Runner. Overall, I’d say this is one of the easiest, and most effective DIY mods you can do when you get your 4Runner. The assurance that it brings is second to none.
In order to complete this modification, you need the following things:
Tools:
14mm Socket
12mm Socket
Screwdriver for hose clamps
Parts:
4-5 Feet of 5/16 Fuel Hose
2x 5/16 Hose clamps
Dorman Diff Breather: amzn.to/46gal0l
Toyota Union: amzn.to/48kn43S

Awesome video dude! I'm definitely going to try and add this mod before I go off road again.
So helpful man! I had this exact issue. You saved me so much money!
Awesome solution! Most people run 10' of hose into the engine bay... Or into the interior... Your idea is genius!
Thanks so much! It was a no brainer when I was looking at it. I like to think if the waters that high, I got bigger problems!
My 2019 ram already had something like this installed. Just got a 2023 Tacoma. Was figuring out how to do something similar. Thank you for the video.
Congrats on the brand new Tacoma! What model, colour, and package did you end up getting? They look like amazing trucks. Always happy to help!
@@looseaxles I got a 2023 Trd off-road 4 x 4. In the process of modifying it myself. A lot cheaper to do it this way. And you still get all the great off-road goodies. Silver with blackout. Sidewinder step bars matte black, full tint and flat locking bed cover,Pedal commander also installed.
@@ParZIVal19D wow! That sounds like a seriously cool build. I’m excited to hear more about it as you continue to build it up - it’s so rewarding to do the work yourself.
@@looseaxles it is. Especially retired now. It’s gonna be a fun truck for the pacific north west up here.
this was a great video! Definitely gotta do this soon although I usually stay away from water crossings
Thanks Hunter! Well worth it. I think there’s some guys that sell the kit for around 30ish bucks on the forums!
This seems like a much better idea than buying the ARB $100 diff breather
100% a complete no brainer!
@@looseaxles is there any really difference between this set up and the ARB diff breather with the "filter"
another banger of a video
It a great idea to move the Breather higher up and out of the dirt and water 💦but the breather is a one way valve only so if you rapidly cool the differential in a water crossing the valve closes and water can get sucked into the housing via the axle seals . swap the breather cap for a small fuel filter and you are good to go
Agreed! That’s a great suggestion as well. I may make an updated video for a smaller filter that fits.
@@looseaxles some ride on lawnmowers have small inline fuel Filters and older cars that had carburettors
I've been looking for my 4runner. It seems the line would rub on multiple spots over time.
You can also put tape on where it would rub. I haven’t had any issues at all for 10+ years doing it this way!
@@looseaxlesThat's a good idea, looking again I feel like this gen has less to get snagged on/rub against than my 5th gen.
@@user-cg7cc7zj3e for sure! I hope it worked out well for you!
What about the transfer case?
The transfer case already has an extended breather that goes into the engine bay thankfully!
@@looseaxles where is it located? Any info you can share?
Bravo 👍
Dumb question but will this work with the sequoias?
No such thing as a dumb question! I would assume the setup would be similar if not the same!
@@looseaxles i just bought sequoia 4wd and I’m new to it. Thank you 🤙
Does the front diff have a breather?
They sure do! They are routed into the engine bay though, so no need to extend them!
@@looseaxles just extended the rear breather and was looking for the front breathers. Thanks for the reply!
*Your video makes me motion sick!*
Haha! Hate it when that happens. I’ll try to move slower for you ;)
