Hoses to no where

[jsbihn]

Everything appears to be OEM like.
In fact the hoses have a small clamp on the tranny to keep them in the proper routing.
These hoses run from the transfer case to the front along side the tranny
The capped hoses are in the front near the engine and tranny
the hoses go back to the transfer case, and connect to it.

Vent hoses for transmission and transfer case. Should also be some for front and rear diff's

[jsbihn]

seriously?
seems like alot of tubing for a vent and that they are capped

btw, is it possible they could leak oil?

Wouldn't think that they would leak

[jsbihn]

damn thats just awkward

as for the leak, yeah i have one now and cant figure out where it is coming from.
Thought when I saw oil on the hoses that it might be them, but there is some oil all over the place.

Oh well.
weird things done by Hummer

I was checking my vent lines at the case while doing my 50k.

What I found weird is they weren't clamped on. I grabbed a zip tie.

I didn't trace them to the plugged end as manual just said check for kinks at tc.

Why are the vent tubes plugged?

[Easy Ed]

I don't think they are "plugged" but that they are a "one way valve" to vent out any pressure/gasses that may build up in the cases from heat and maybe also to keep the pressure from trying to go out any shaft seals which would cause leaks, just a guess on my part
