Wow guys, the mic I used on this video obviously did NOT work out. New one incoming.
Two things I did different with this mod is I routed it into the rear tail light so no drilling required. Also you can reuse the diff breather no need to buy a second one
Yeah I didn’t drill here either. Just routed past the rubber surrounding the fuel filler. You can reuse it, but often times, as I was told by a shop who works on diffs, the OEM breather valve gets clogged with dirt if it’s used off road a lot. It’s so insanely cheap to replace that it just makes sense to do so while you’re in there.
The taillight idea was another one I was considering but I have aftermarket taillights and they didn’t allow it as easy as the OEM Ones. It’s a great idea though!
Great video. Thanks for sharing.
Awesome thanks! Cant wait for engine breather
Great video. The gas filler cap area is a common area and a great one at that. The other people either making fun of you for placing it there or worried that you placed it there are worrying for no reason and are misinformed and probably never take their rig on a gravel road let alone actual off roading lol. I plan on doing this tomorrow and plan on doing it exactly how you did. Thanks for the video man!
lol yeah I don’t worry/think about this mod at all, which is just the way I like it. Thanks for watching!
Great video. Shed another 10 lbs by removing that OEM air pump back there for the bags that you have removed.
Thanks! Been meaning to do that!
I routed mine to the engine bay
But the valve cap is pinned isnt it? Because it's basically a check valve so keeping it tight would mess with operation right?
I'm looking at getting a gx 470 to start building out. Do you have any recommendations on which year I should look at? What about mileage? Thanks, and enjoy watching your videos!
I recommend checking out this video where I go over all the relevant info on the 470: th-cam.com/video/hlAl3hm94iM/w-d-xo.html
Should be enough to get you started with your search. Good luck!
Hey, thank you so much!
Of all the available areas why inside the gas cap/filler? Wouldn't that defeat the purpose if you accidently spill gas on the breather? Happens to me once in a while during fill-up. I routed mine up as high as possible along the truck bed right on top of the spare tire and stuck it in one of those precut holes. And just so you know if you lift the rear cargo carpet, there are holes that goes right into the cargo. I would think that would be the best option. The reality is, if your able to get water up that high then you must be crossing a lake or in a major flood.
EDIT: I have a 4runner but same idea.
Not worried about fuel spillage at all, it sits clear enough for that not to be an issue. It was convenient for me to route, high up, and works great! Plus, it is more insulated from dust than it would be underneath the rig and more accessible if I want to change out the breather valve down the line.
Did you make a video on the front diff breather?
@@WendzDarKnight08 the front differential has an extended breather hose that is elevated into the engine bay from the factory. It is not as much of a risk as the rear but if you want to extend the front breather hose, I believe it is somewhere in the driver side of the engine bay. To find it, you can remove skid plate and look on the top of the of the diff to see where it plums in/trace from there.
lmao diff breather in the fuel area. oh man that hilarious 😂😂
Why?
What about sealing the cabin? Most cars take on water inside if they do a water crossing.
Hah if I find water that deep here in SoCal, I deserve a little moisture. But for real, I would not want to try any crossings that would go far enough above the floor to cause water intrusion. There are a lot of control units mounted to the floor that i don’t want to fry. Cabin sealing is a great idea
I thought the rear diff breather was an open valve that closes/ sucks in when the hot diff hits cold water. Creates a vacuum that closes the valve, so you don’t suck in water??
Yes, that is the intended design. However, even if it works perfectly (which is a big IF on these old trucks) it will at best mitigate the inflow of water, not prevent it 100%, which is the goal here. Many GXs over 8-10 years old that off road regularly have stuck valves anyway, so it’s best to at least test/replace it if you think you might cross deep water, or even better, relocate it and don’t risk water ingress (however minimal) every time you make a water crossing.
What are the threads on axle? NPT? If not you should use Teflon tape.
I figured that if OE didn’t use Teflon tape, it should be fine. I’ll do more research into whether it’s NPT.
OEM is also brass and with brass you don’t usually need tape.
@@Fremlin gotcha
@@Fremlin from seller: “I would recommend using Teflon tape. I don’t think he is correct about the OEM being brass.”
Where did you get that new cargo net piece?

Is there a FRONT diff breather as well?
Yes but it’s packaged pretty high up from the factory. You can extend it if you want as well though
Even an idiot like me can do this!
I love how you wasted money on a Molle panel for the tail gate 🤣🤣🤣🤣
Looks better than a saggy net 🤷♂️
@@lexus_offroad_adventures definitely. Mine was destroyed. I put a table in but was looking at the panel
I need to do this asap. Lots of water here in the pnw
For sure. I avoided it for a while since I’m in SoCal but we just got a bunch of rain this season and there are some deep puddles on trails. No point in putting it off tho, super cheap and easy.
@@lexus_offroad_adventures do you get a cut if I buy it from your link?
@@shlomogoldstein3373 nope, no commission or anything in this one. This guy (I think his name is Miles) just runs a small business and supports the GX community so I used his kit and posted his link.
@@lexus_offroad_adventures was hoping you would. I'm going to order one today
