Where would be the ultimate location for axles/transfer case/transmission vents ?

[Jean-Seb]

I'll be relocating the vents (some day) on my vehicle and I ask myself; "Where would be the ultimate area of the vehicle to relocate them to ?"

So here are my ideas;

1. Move the front ones (front axle/transfer case/transmission) to the firewall as high as possible in the engine compartment, and the rear axle vent to the gas filler door. (Seems like a good idea but could be higher in my opinion.)

2. Move the front ones outside the vehicle near the common snorkel inlet location (in a little covered but not sealed box to protect from the rain hehe) and the rear axle vent to one of the rear roof corners.

3. Or extend all the lines and move them inside the cab as high and rearward as possible. (Could work but I'm thinking of the smell and possibilities of leakage if the vehicle is rolled, so not that much of a good idea. )


Any ideas or thoughts ? Where did you relocate yours ?

Thank you. :snorkel:

As high as possible! It really depends on how much water you plan to cross.

I have my front vents at the top of my firewall. If I get into water deeper than that, I have some serious issues to work out.

Thanks for the input ! It would act more like an insurance policy, just in case a dip or hole in the riverbed wasn't seen during reconnaissance.

After some more research I found this out; http://www.4crawler.com/4x4/CheapTricks/WaterProofing.shtml#Breathers

The third paragraph below the taillight picture, it says what happens if the vents are too high. :Wow1:

I'm thinking that if the oil got that high, it (rearend) was way over filled.

Diffs will usually puke to get down to the correct level if they are over filled.

I put the rear one behind the top of the tail light. Lots of room, up high, and the paint was really clean (less dust).

At least as high as the breather box in front..

As high as you can get the rear.. Maybe above the fuel tank..

If you're anal about dust, slap one of these on the end of the lines.. $10 or so each..

Thanks for the replies. I have seen those vents that look very trick, I might go with those. http://www.northeastxt.com/vent.html

I'll probably go with option #1, as it seems to be the most common and trail-tested alternative.

if you roll your vehicle, a dribble of gear oil on the headliner will be the least of our worries.

True.

I was more worried about major spills. :coffeedrink:

ran mine into the cab on my 85, put a small filter on them.

So I think I can how that works. Just fit it on the end of the line and it can expand/contract without ever letting air or water in or out???

Did you have any significant issues with smell ?

One inch higher than your electronics :ylsmoke:

I ran my fronts to the top of the firewall, the rear is behind the taillight - if I get any deeper, that'll be the least of my worries
