The max fording depth of my '15 4runner is a secret that Toyota will not disclose.
If anybody has found out what it is, I would love to know it.

It's not posted because there is no magic number. You can hydrolock and drown your engine in 8" of water if you drive through it too quickly, or you can safely navigate 30" for short periods if the conditions are right and you know what you're doing. The general rule if driven slowly without wake is about 24-30" for short periods as the air intake is on the inside passenger side fender about 3/4 of the way up (the slots at the front of the fender liner). So if you have a 31-32" tire that's about 24" +/-lift.

Yep. Had to go through about 30" this past summer to rescue my in laws trapped in a flood. Parked the 4Runner long enough for everything to cool down, went through about 100 yards at a few mph. No wake or bow wave, no splash. Was in water about 20 seconds. No problem or worries. Water had very weak current.

Here's a picture that I find interesting.....no snorkel visible.
In my mind, I'm guessing this guy will have a problem...based on the bow wake, the angle of the vehicle, but most obvious, the water on the windshield...that's a deep ass hole.
I understand the concept of water crossings done correctly, but this picture doesn't strike me as one of them.
I doubt it made it across....but just my own opinion.

LMAO...My question is wtf does he think the trailer is going to do, act as a rescue buoy? Unless your name is Captain Nemo, I'd also advise against this with your Vehicle.
As a learning note this is why you walk water crossings first.

I hope we get to wheel together. I can tell you know what you're doing. Growing up with a Wrangler in FL I know the absolute shit show water is. I had axle seals on my front end and that ***** still let mud and silt into the axle tubes. I avoid water like the plague.
That said, I've been through some deep shit in my T4R merely out of necessity. Think water over the hood for a few seconds. It's all about how you do it - I have friends with brand new Frontiers who hit every water hole at 30mph thinking it's so cool to make a splash.
They've never changed any fluids, and I bet they're in for s big surprise when they do.

i've personally been this deep as i submerged into a water hole in the outer banks. once the hood went under water i floored it to pull out if at all possible. came out and no water in my airbox believe it or not

Has anyone ever actually found water in the rear diff after a water crossing? Or ever? Toyota has been doing this for a very long time. The diff breather valve has been used for a very long time. I've yet to find any water in any of my axles ever. I've done breather tubes on quite a few, but i'm not sure it's really necessary.
I've been in water over the hood in my '84 - and it killed the distributor first. Don't do that. I was able to winch out and still drive it home, but it was a long day. I'd guess in a 5th gen you might get lucky and have an intake sensor shut it down before sucking in water, but I kinda doubt it. My guess is an over the hood water crossing would result in buying a new engine.

It does happen. I've seen the result. It's not from water coming in the one way valve. It' is when the diff is really hot and you submerge fully into water . The drop in pressure and vacuum cause a suction and it seeps in through various seals... You need a breather of some sort for sure, but the little one way is probably good enough for 99% of runners adventures.

if you need to go deeper than a diff breather you should basically start disconnecting, greasing, and reconnecting every electrical connector

and removing carpet, running a snorkel, installing drain holes, etc. :tongue1:

Did Toyota do that for the FJ?

The drain holes are there. It's also a good idea to periodically check the drain plugs are still inserted. Don't ask me how I know about that one.

I think every connector or nearly every connector has an o-ring seal that would do a pretty good job of water protection. I've yet to open one that isn't on my 5th gen. But there may be some that aren't. A little silicone grease on the o-rings could help ensure that they aren't compromised by deep water crossings.
The biggest problems I've had over the years is the mess. Water and mud in the carpets is a HUGE PITA to clean up. Especially the thin gooey kind of mud that comes through the drains under the carpeting and gets in your seat tracks and such. It's just not something I ever want to try to clean out of my daily driver. Unless it's absolutely necessary, I'd find an alternative route around the mud/water. My personal stopping point is when the water hits the floor pan unless it's a very quick in and out where I won't get water inside the cab. Otherwise I've made a mistake and should be in my FJ40 or hiking.
This is my limit. It's a daily driver first. As much as I love to test the limits, as I've gotten older and lamer (or wiser depending on you view point) I accept my limits a little more.
