- Are you doing water crossings or hitting mud holes? If you are, then you should extend the breathers on your differentials. Not doing so, you could end up with water in your differential fluid. This ARB kit is great and easy to install. Click the link below to grab on! Thanks for watching!

Just did mine on my 4th gen and 4 of my 3rd gens love these Arb Kits they are well worth the price 12:21
Just ordered mine. With a 2 inch lift and 285’s, will try and run the cable without jack lift, if able to run them, will do it home. Wish me luck!
Awesome vid, thanks.
Thanks for the feedback!
Great video !!.. nice work
Thanks Edwin!
Great content gentlemen
Thank you!
There are a total of 7 breathers on 4Runners with a factory rear locker and 6 breathers with no rear locker. 4Runners with a factory rear locker have two rear breathers that need to be relocated higher; one for the diff and one for the locker. I recommend you use the rest of your hose for the locker breather.
Agreed that most people don't need to relocate the other five breathers; front diff, front diff actuator, transmission and two from the transfer case. Those five are quite high. But good to relocate the two in the rear; rear diff and rear locker breathers.
Good to know! Thanks for the info.
From all my research once you replace the rear differential breather with the arb kit the diff is then permanently open and since the rear locker and rear diff share the same space doing the rear locker is unnecessary.
M6 bolts fit in the arb Breather manifold I installed Rivnuts on my firewall and bolted it with m6 1.0 thread bolts 2:54 it says on the side of the box you can use m6 or 1/4 inch bolts
Would love to see the front diff breather in the engine bay
Its located on the driver side. Between the engine and strut tower. You can see the 2 breathers there.
Interesting it's nose rubber hose with barb fittings it's more Shark bite fitings
The included screws were plenty long enough to secure into the firewall, the metal in the body is less than 1mm thick, there was around 4mm of thread to screw into the body
Porque usas una sola manguera? No deberia de ser 2 una para la transicion delantera y otra para la trasera?
No link in description for the breather kit even though it says click link to grab one of these kits
Updated!
@@yotaxpedition cool was just wanting to help
What size bolt did you use exactly? I’ve been interested in installing this but the self tappers we’re turning me off.
M6x1.0 is the thread. 35mm long.
Thank you!!
Does the transmission breather use the same type of breather cap as the diff?
Yes but it is extended up behind the engine and firewall.
Wonder if this will work on 3rd gen and 4th gen 4runners?
Yes, it will work the same.
@@yotaxpedition sweet
Do all 5th gen 4Runners have the front dif and transmission breathers the same as this?
Yes, they should all be in the same location.
@@yotaxpedition sick!! Thanks that gives me some peace of mind lol. Now I have to do the rear diff :)
Why wouldn’t someone just make a 1 way release valve… that way you wouldn’t need a dif breathing kit.
That would make to much sense lol.
Air needs to be able to escape as the differential and axel heat up and then re-enter as they cool. A 1-way release valve would create a vacuum once once the differential and axel cooled down, eventually compromising either the axel seals or the differential gasket and causing a leak.
That's actually exactly how they are stock. The issue is as @andrewl3728 said that it creates a vacuum due to temperature change which sucks in water from the axle seals. Explained in more detail here: ua-cam.com/video/hiRTNTY_U6U/v-deo.html
