Water fording breather tubes

Sorry it’s a bit of a rando question but I keep seeing cars trying to drive through flood water on social media and it got me thinking that it might be prudent to check what the black beast could safely ford though. I was thinking maybe I could add breather tube extensions to anything that needed them so water couldn’t get in where it would cause havoc, has anyone done this or is it pointless? Pic attached to make it less boring

Pointless? No. The stock breather tubes are real short, right on top of the diffs basically. Any extension would help.

Breather Locations Requiring Extensions

Have a trip out west coming up and will more than likely have some deep water crossings, when I looked at the front diff the breather it was essentially a 1" nub. If anyone has modded these can you hook me up with a round about location for any others I will need to extend and the hose...

An extension wont improve anything they are designed to keep the water out with the gortex design.
 
I always saw the old wife’s tale that with a hot differential and sudden immersion in cold water causes negative pressure that will suck water through the seals or breather. I don’t ford deep water so have no personal experience.
 
Extended mine, front to the highest point under the hood and rear above the taillight…no way I’m trusting Gore-schmex to keep water out of a diff when it fails in short order to keep it out of boots invariably.
I did put the factory thing on the end but after small fuel filters, figured it couldn’t hurt though no faith in their stopping dust once the fabric degrades and it will.

Don’t know.

If I was crossing deep water often I’d likely extend them, but for the typical once in awhile creek crossing the factory breather are good it seems.

Wasn’t the gor-tex breather on my rear axle, a little wobbly cap setup on the end of a hose that was barely attached to the pumpkin…so badly attached that water would def had got in launching the boats on lousy ramps.
See the link above..

I extended my front diff breather up into the engine bay, and the rear diff breather up by the tail light.

The front one was really short, but does have the gore-tex breather. Still, I feel better having it up high in the engine bay.
Rear one was the wobbly ball thing Poolmonkey said. It wasnt too low, but i put it as high as possible.

You could do the same for the transfercase and transmission, I just havent got to it. I figure those are tucked a bit higher above the frame.
