Water crossing

With the recent flooding we have experienced in FL I'm wondering if anything needs to be done if I have driving through water up to my floor board? Is everything pretty well sealed up? Should I drain any fluids?

Thanks

 

You'll be fine. Good luck with Irma.

 

Rear diff. Fluid... unless you've done the breather mod.

Oh wow, I wondered about the rear diff.... I didn't realize it wasn't sealed. So looking at the breather mod the stock breather will let water in?

 

Thanks, things aren't looking good for us here in FL.

 

Not nessarily the breather but what you have is a spring loaded vent type deal, it can create a vacuum when you enter water and pull water in through the axle and such.
It's just a matter of relocating up higher on the truck. And in case your wondering the front breathers they are already up high in your engine bay.
Go through the thread I linked.

 

read other reply from Radaninja

Its a vent, not a breather. Asked the techs at toyota when I was in, so yes it creates a vacuum.
I relocated all of them even higher. They're all now beside the battery, front/rear diff, trans, tcase.

I have the ARB breather kit, but then again I also go off road and do water crossings pretty deep. Snorkel is on the list.

 

@Joe23 Do you have pics of the install? I have the same ARB Breather kit and was wondering how others have positioned it. Are any other parts needed for the install?

 

Look through here. https://www.tacomaworld.com/threads/my-differential-breather-mod-photos.111954/

 

If you have the time and parts relocating the breather on the rear diff is a good idea if you plan on submerging the rear diff often.

That said I wouldn't be too worried about driving through deep water caused by the recent flooding if you aren't able to get it done. Your truck is new and your axle seals should still be in great shape, so the odds of creating a vacuum in your rear diff strong enough to pull water past the seals is pretty small.

But regardless if you are driving through lots of deep water often draining/changing fluids isn't a bad decision. Never know if something isn't sealed quite correctly and letting water in.

 

Do you have pics or can provide direction on where the stock breather locations are for the front diff, trans, and tcase?
Thanks in advance!

 

Guys I put a link up here twice. There's tons of pics in it.

 

ya its a pain in the fuckin ass lol.

Toyota uses 1/4" hosing where the ARB one uses 8mm (5/16") tubing.

Also there are a total of seven lines needed to connect to a four port part.
Mine was done as follows.

Electrical breathers on trans/tcase joined together with a Y fitting and then added to ARB
Rear diff+Front diff joined together and put to one port (there are two for the front diff, one is a vent in, other is vent out as per OEM, I Y'd these together as well)
T case breather to one port
trans breather to one port

The two front diff ones are by the frame near the cat.
The other ones are by the battery

Give me a minute I'll go take pics and update of what mine looks like now to a degree. Sorry but I am not dropping my skids lol.

 

Thanks for all the detailed information. Look forward to any pics you have and totally understand about not wanting to drop your skids!

 

I only had the front skid on when the breathers were done and that one has to be dropped as well. But I currently have all of them on and they are a PITA to do so ya.

 

Never done this mod. Never had an issue.

 

Installed next to brake reservoir.
Red is t case and front diff electronics
Above is the rear and front diff, the other two lines are t case and trans
Factory ones I tapped into
Y Fitting used to join two electrical breathers
Looking down beside fuse box some of the OEM ones are around here.
T fitting under the red hose is for the two diffs, joined then go to the ARB port
T case electronics breather location
Looking up into driver fender you can see the red hose where I ran up to the engine bay
Driver side behind the front cab mount, can see the T case hose and the hose coming from rear diff



Most of the fittings were from Princess Auto (very similar to Harbor Freight)
I actually just picked up a 100ft bundle of 8mm tubing from a pneumatics and hydraulics hose supplier. Was hard to find 8mm stuff from princess auto so went to a supplier. Wasn't the cheapest stuff but oh well.

I'll be needing to extend the rear one some more when I do my lift.

 

Never did the mod, but luckily Toyota installed an automatic seeping differential that bleeds out all the excess moisture.

 

Wow @Joe23 thank you for getting all of the pics and recommendations on where to get the fittings and hose.

 

no problem dude.
And the trans and t case are in the back of the engine by the down pipe.
Royal bitch to get at.

Can't find the pics on here but search around there are pics of where they are.

I'd take pics but mine are no longer there lol
