Two or Four Breathers?

[arod Lurker Find all posts View Profile Close arod]

I've just had my 2023 GXL put in for diff breathers.

I had assumed since I was going the effort that they would install them on the diffs, transmission and transfer case, however they've only installed them on the diffs, saying the other two were already high enough.

I'm no expert and not planning on doing anything really extreme, however wanting to understand if this is sound logic or just lazy? I assumed since I was going to the effort of getting them installed that they would install them on all four.

Thanks

My understanding is that the front diff, transfer case and transmission breathers are all pretty high up in the engine bay. It's just the rear diff that perhaps need extending. So I guess the logic is sound.

Agree with grinbot… all are quite high accept the rear diff.
Extended all 4 on the last Prado. Haven’t bothered with the new one. If it’s that deep now, I’ll take the boat.
It’s one thing to fit a snorkel and breathers, but there’s so much more that gets stuffed in deep water/mud that it’s not worth it.

Nearly all kits now come with 1/4inch John guess pressure hose that you use on water filters etc, really not sure how this goes with oils/fluids. Personally I can see it breaking down quickly and there being an open end, causing more of an issue than not having an extended breather.
