ARB Breather install.
You can DIY your own relocated breather for less. But I like the option that I can clean the filter and add more if need be later for any reason so I purchased the ARB Differential Axle Breather from
Arb Diff Breather Kit
Drop your tire to have MUCH more working room. Saves a ton of time by dropping the tire.
Most of my intel for the install came from,
Rear Differential Breather Mod For Dummies
The ARB Kit included the fittings to plug into the Diff.
I purchased from autozone a Tee fitting kit that included a 3/16 x 3/16 x 1/8 tee fitting.
I have a trail edition, which has a rear locker and has a breather itself so I wanted to Tee it into the same line going to the ARB breather in the engine bay.
Here you can see where I put in the Tee fitting and the wrench on the old breather.
You can also see the black ARB hose line, before I moved it higher above everything else and secured it with zip ties to some brackets.
You have to be sure that the hose will stay away from exhaust so you dont melt a hole into your line!
For the breather in the front I was worried about its placement in the engine bay so I put a bar to hold the hood propped open and then disconnected the gas strut.
once the gas strut was loose I knew that it would clear the breather when the hood is closed.
If you are doing a DIY relocated breather you can order from toyota a 90404-51319 union.
this is for the DIY person running 1/2" fuel line hose
