Toyota Tacoma | Diff Breather Mod | Diff Breather Extension | (2017 Tacoma)

- In the Garage today we are extending the tiny Diff breather on the rear axle. The rear axle diff breather on the tacoma is super small and right above the diff. By comparison, all of my prior jeeps had longer/higher diff breather set ups. The reasoning for extending the hose and re-locating the breather is to try and ensure no mud or water gets into the diff. Many people argue it can't happen, but I have seen enough diffs full of muddy water. I relocated my breather to the the gas cap area. I kept calling it the gas can in the video, sorry. Its a good spot for it so you can see it every time you fill up the tank. Some people install it behind the tail light. That will not work for me. I'm to lazy to remove the light every month to inspect it. This mod is useful if you spend time in muddy areas or have to regularly go through puddles above the center line of the wheels. This is just cheap insurance and a fun little project to protect that diff. Thanks for watching, all links below.

Hit that subscribe button to stay up to date on all my videos!
Dude I saw you liked my post on tacoma world of the BAMF sliders. So ironic bc I was watching your video on how to install the sliders lol. It helped so much thanks man!
Ha, nice man. Thanks for watching. You have a crazy good channel by the way. I will put my son onto it.
Great video and clean install! Happy Wheeling!
Thank you and thanks for watching.
Semper Fi Devil Dog, great video. I've been wanting to do this to my 2014 Tacoma, this advice will help a lot!
Thank you.
Clean install like always. Now I'm going to redo my breather mod and route it to the gas cap. Idk why i didn't think of that!
Thank you for the kind words, good luck with your install.
Such a clean install nice man! I need to do this lol
Appreciate Bubs, thanks for watching.
For Firestone air bags I ran the air Valve to either side of the trailer plug in. Nice mod, Thanks
Thanks for watching.
Excellent work, thanks for the informative video.
Thanks for watching.
Great video and now I have a mission!
Thank you.
Nice job dude! You pay attention to the small things, like I do. So appreciate how you work 🤙
Thank you for the kind words. I’m trying.
Nice DIY very clean
Thanks, appreciate it.
nice video man. i ordered the parts already. project for tomorrow
Thanks, appreciate it. Good luck with the install.
Thank you for the detailed information!
Thanks for watching.
Awesome cheap mod
I was looking into the arb one but I like this idea better
Appreciate it, thanks for watching.
I did a version of this mod without drilling a hole through the gas filler neck skirt. I had removed forward bed tie-downs so the nut-certs were available for use from the back side. Upon removing the skirt around the gas filler neck, then you can clearly see and access the nut-certs. I used an 8mm screw and fashioned a hose clamp from some of that metal plumbers strap (metal tape with holes) and attached it up as high as I could get it, right up to the top edge under the bed (well above where it would be if you put it in the gas filler neck skirt. It was simple and quick. FYI, if you want to keep the tie-downs, get a longer 8mm screw then you can use a nut from the back side.. Zero drilling and the vent is up very high. Just my two cents.
Thanks for the heads up and for watching.
Awesome!
Thank you.
Good info. If I had thought of this before I relocated the factory valve to another location, I might have given this a try. Easy and guessing about a six inches higher than my location. Not sure it would work on my vehicle since it is not a Taco.
Thanks for watching.
Awesome
Thank you.
Hey brother, one of the reasons for doing the diff breather is, not only to relocate the breather valve (stock) higher and further away from submersion but also to replace the valve (stock) with a free flowing one like the ARB. Otherwise reusing the same check valve will still cause the same sucking action of water/mud into the diff through the axel seals when a hot diff is dunked in cold water/mud. With a free flowing valve, the pressure in the diff will remain constant and there will be no change in pressure and therefore no sucking in water/mud.
You Dont have to believe me lol but check it out for yourself. Just though I'd point it out in case you didnt know.
Thank you, I will look into it. So what you are saying is I should also replace the stock valve I relocated into the gas cap? The new union at the diff is free flow. Thanks for the heads up.
@@ClassyTacos yes replace the stock check valve with a free flowing valve. When you submerged the hot diff in cold water the change in temp will still cause the pressure to suck the check valve (stock) down/closed and that pressure could cause the axel seals to pull water in and the diff breather may not work as intended. With a free flowing valve at the end of that hose the air pressure in the diff will equalize with the atmospheric pressure and no "sucking in" will happen at drastic temp changes when submitting the hot diff in mud or water
@@ClassyTacos @Overlandbound explains it much better in his video. He runs the ARB kit, I do as well. I'm sure you can find an alternative free flowing valve and use that just as well since you already ran the hoses and a new union
@@AnthrozoologyTV I see tons of these vids that should be removed or edited. Relocating a check valve (pressure release valve) does nothing to keep water out. It is a release valve. It needs to be replaced with a breather of some sort. Literally dozens of these vids that mislead folks into thinking they are doing anything to keep water out. The idea of a breather is to prevent a vacuum in the diff that can draw in water through seals and bearings when the diff is cooled rapidly in water/mud. Just moving the check valve effectively does nothing to prevent that vacuum.
@@oldmanhare does the front diff needs a breather too?
Great idear
Thanks a lot
Great video, very helpful! What leaf pack are you running?
Thank you. Running the Old Man Emu leafs, they are super noisy.
I did this a few days ago...I have a DECKED so I ran the hose straight up into the bed and secured it there...I had the right half of the DECKED out with no drawers because they weigh so much and for more storage...I never plan on going into water and deep mud unless I have to.
Thanks for watching. Good stuff.
On my 2nd gen i have bed cubbies that make it hard to fish above wheel well so i may mount it at my rear tail light .. no cap ..
Thanks for watching.
Can you do an episode or thoughts on the switch pro 9100 of any of their other products.
I appreciate you asking. I went with a different option from the get go. The OE Aux Power tray with OEM style switches. I like the OEM style switches in the cab. Here is the install for that- th-cam.com/video/nxr0R5WTf4w/w-d-xo.html
The switch pro is clean, and works well, just not for me. Thanks for watching.
Looks good.....is there one for the front diff too?
I have to look into it but I believe the front diff breather is already high. I think it is tucked in the back of the engine bay mid way up the fire wall. Thanks for watching.
Did the new Union piece thread all the way in for you? I stopped with a couple threads showing because it was making me nervous 😂
You're good, No need to hammer down on it all the way, it gets tight. Thanks for watching.
@@ClassyTacos thanks for the reply! 🤙🏽
not sure if you have a video on it or not, but what is the purpose of the diff breather outside of showing if the diff is flooded and what do you do if it does fill with water? I know mud is horrible for stuff like this and I am sure the answer is to take it apart, clean, regrease and run but idk. I am just beginning my offroad adventuring and am trying to learn as much as I can about issues that may arise and how to fix em. Thx!!
The purpose of a breather is to allow the diff in this case to release pressure which builds in the diff. For example, as the diff gets hot with rotation and is cooled suddenly by water like hitting a puddle. It gives the air in the diff a place to escape as the fluid changes temps/expands. I'm no expert. That is how I understand it. Thanks for watching.
@@ClassyTacos thank you! I appreciate the pointers! Loved the video, I’m gonna be doing the same mod here soon
How has this worked for you the last couple months I see in the comments some ppl are saying to change out the breather also is that really Necessary or is it still OK to keep the stock breather..
No issues so far. Everyone has different ways of doing things. They all make sense. The open breather is cheap and easy to swap out in case you change your mind down the road.
If the union and the hose are properly installed and high enough on the truck you shouldn’t have to check if water is coming out the only way for water to get into your rearend is threw that breather
No this is incorrect, it can get sucked in through the axle seals with a quick temp change. look it up. Thanks for watching.
Do you only have to do this for the front? I just bought a 2023 TRD off road Tacoma
It's for the rear, the front diff breathers are generally high enough. They should be on the left side of the battery tray area.
What are we watching for to come out of breather on a regular basis? Foam, water, oil???
If it ever did puke up, it would be more like a frothy, watery oil mixture. If it's just oil, the diff may be overfilled. Anything else is enough to look into it further. Thanks for watching.
Yeah but what happens when you put gas in that hole?
Ha, I needed that today. Thank you.
What is your suspension set up?
Kings 2.5 resi with adjusters, Dirt King UCA & LCA, Darker Springs with Archive Garage Hammer Hangers. Thanks for watching.
What size is that fitting on top of the diff
If you are talking about the new fitting look up Toyota union. I have a link in the description. As for the size and thread pitch, no idea. Thanks for watching.
What about the front differential?
The front diff breather is high from the factory. Both the front diff breather and the ADD breather are up by the battery. Thanks for watching.
@@ClassyTacos thanks! Love your channel!
What about the front?
The diff breather for the front diff is already kinda high. Its usually half way up the firewall or its tucked to the right of the battery.
No teflon tape?
Can you elaborate on your question sir? No tape for the install.
Threads screwed into the diff need Teflon tape or paste.
