ARB Differential Breather Kit Installation | Toyota 4Runner 

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!

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.

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

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

Great video !!.. nice work

Awesome vid, thanks.

Need to relocate front and rear diff breathers inside the cabin if you plan on going in water deep enough to need a snorkel or you will suck water in your diff.

Great content gentlemen

Interesting it's nose rubber hose with barb fittings it's more Shark bite fitings

Would love to see the front diff breather in the engine bay

Porque usas una sola manguera? No deberia de ser 2 una para la transicion delantera y otra para la trasera?

Does the transmission breather use the same type of breather cap as the diff?

What size bolt did you use exactly? I’ve been interested in installing this but the self tappers we’re turning me off.

Do all 5th gen 4Runners have the front dif and transmission breathers the same as this?

No link in description for the breather kit even though it says click link to grab one of these kits

Wonder if this will work on 3rd gen and 4th gen 4runners?

Why wouldn’t someone just make a 1 way release valve… that way you wouldn’t need a dif breathing kit.
