Extended Front Differential & Transfer Case Breathers

DevinSixtySeven · #1 (**permalink**) 09-24-2002, 02:34 PM

I'm going to detail my process here. Haven't done it just yet, going to tackle it this week or weekend so I can go play in the water.

The front breather comes out to the right of the front pumpkin, and appears to have a hardline attached to it, leading to a harness/tube bracket which also holds the ADD Actuator signal line and a vacuum hose. The breather hardline terminates to a "Breather Hose", destination currently unknown but not for long.

The extension mod I'm going to complete will involve checking to see where that breather hose terminates, and if I don't like it, it's going to come up to the top of the engine compartment firewall like the rear breather.

Details and hopefully pics to come.

Yes, there's a breather here, too.

Like the front differential, this already has a hose attached to it. I will find out where this hose leads and resolve the need/lack thereof for a t-case breather.

The location is the same on the manual and automatic transmissions, it is a square plate with a valve stem pointing right, located on the top of the t-case.

More details later, when I actually get under the truck and poke around.

Sean:

Take a look along your inner fender panel on the driver side. Look just below and behind the battery. See those (2) hoses coming up with the metal caps? I think that's what you are looking for.

finally got the chance to poke around today, and you're right

.

the smaller of the two hoses leads directly to the breather on the a.d.d. unit, you can trace it easily even if you have a skid row skid plate.

the larger of the two hoses should be the transfer case breather hose, it is factory extended as well.

both hoses are located high enough that 33" of water shouldn't give you any trouble (and besides, what the heck would you be doing with a tundra in 33" of water??).

thanks dude

thanks to dude boy for the heads-up on this one.

in the engine compartment, driver's side, between the block and the wheel well, there are two hoses terminating in breather caps. the smaller of the two is your front diff breather, the larger im pretty certain is your transfer case breather (i found both ends, but i'd need a little tiny mirror to trace the middle, it goes over the t-case and tranny).

if you've done your rear diff, you should be clear to go play in the water
