The diffs are sealed and don't have breather tubes
Don't know about the gearbox but I assume it is above the wading height.
Pretty sure they would have driven through that many times prior to make sure everything was OK
Whaaaat? What kind of sorcery is at play here? Don't all axles have to vent air pressure? I have a feeling I'm about to learn something new...

I’m guessing they knew exactly how deep that entire path was because it would have been real easy to destroy a truck in not much deeper water.
Yeah, for sure. But the same could be said about every water crossing we do! Unless you are the guys from "The Story Till Now" (below). No one tested this before they took the plunge, and that river was moving pretty good. If it suddenly got much deeper... Go to 12:12 in the video for the good stuff:

I too thought so and we had a lengthy string on here about diff breathers some months ago.
So I asked Ineos dealer and he told me they are sealed

I'll look for the thread...

Okay, I read the thread, including the post that says that the axles are sealed, but I still don't understand how the axles deal with changes in pressure. It has always been my understanding that without a breather tube, the increase in pressure within the axle as it heats up would blow a pinion seal. And secondly, that these breather tubes need to be extended to avoid sucking in water during a water crossing (or mud crossing). I put the front one up high in the engine bay, and I take the rear one up into the space between the walls of the bed of the truck (Toyota trucks have little cubbies in the bed of the truck, and they have pre-drilled holes you can use, so you don't even have to drill into your sheet metal.

I don't understand how a sealed axle can avoid the issue of changes in pressure (both while heating up and while cooling down).

I don't understand either. . .sounds like hocus-pocus.

Ever seen what happens when a breather gets clogged and a hot axle drives through a deep puddle or water crossing? Water gets sucked in the axle seals and eventually grenades the diff.

Could be like this?

With a bellows. I'm just guessing, I don't have any solid info. However, I bet DCPU has a schematic from somewhere...

@DaveB looks like Ineos decided the ship would be to slow to get your Grenadier to you. They are driving it to you. They just have to put it reverse to roll off the miles.
The wrong colour, I think it's mine...Scottish White and looks like they have thrown in a roof rack...bloody beauty

Wow - that was a significant water crossing. This is the first video of the Grenadier that I find truly impressive. I don't mean to sound like a jerk, but everything else I've seen it do has left me with the same reaction, which is "Sure, that's what a solid axle, off-road vehicle with a low-range transfer case should be able to do." I haven't seen the vehicle really pushed yet in the rocks, and I've done enough technical rock crawling that I've been a bit disappointed with the off-road videos. This was great! Maybe they are just getting warmed up.
You may be disappointed then if you expect it to be a technical rock crawler out of the box, it was designed to be a tough and long lasting work vehicle that would also suit overlanders, it wasn’t designed as a tough truck rock crawler. Not many if any vehicles do that stuff well out of the box, almost all require some mods like lifts, bigger tyres, rock sliders, uograded bash plates etc, pretty sure the Grenadier will be the same, although possibly with a better platform to start from than many.

Yup, we are all pretty clear on that, but thanks! :)
