Gonna bite the bullet and ask a stupid question.

So now your backing off from your submerging bs.

Again, what part they can get wet don't you understand ??
It was you who said submerged, not me.
Your the one who said they get wet and blow apart.
Everyone has seen your stupidity.
Shut up kid, go hide in the garage when it rains.

 

They can’t get wet though. Any water in the bearing will destroyed it in a very very short time. Submerged or not, if they see any water the bearing will not last. I stand by that 100%. I had to replace quite a few on my 4.0. Catch a splash of water up onto the front of the engine, and if any of it gets to the pulleys, they’re going to be toast. Those bearings comes with a little bit of grease in them. (Not water).


Kind of sounds like you’re agreeing with me, but you don’t want to admit it. I don’t understand what you’re getting at.


Nice try on the insults, but I’ll hit back with facts

 

Yawn, your trolling.
Your words, any water.
Derp.
Guess all those people on YouTube going through water with snorkel kits are stupid and don't know what they are doing.
Guess getting a engine wash ruins things.
All those pressure wash i had done on cat and Cummings motors ruined them, nope.

The bearing system is not open, a splash of water is not going to infiltrate it.
The belts can handle getting wet.
Your own words was they get wet and are done.
If you are subjecting the vehicle to environments the apply enough pressure for water to enter pass the seals into the bearings then you have far more issues to worry about.

As for insults, you started that also.
Reading is fundamental, but not for you.
Stop seeking attention online, get a pet.

 

Gross. But appropriate.

 

Some are more susceptible than others. We’re taking about Tacoma ones. They’re very prone to this. Feel free to look into it. And I can speak from personal experience on that.


and yeah...all the guys driving underwater submerging their engines are absolutely going to be replacing more pulleys and bearings than under normal conditions. If you don’t understand why or how, there’s nothing I can do to help you. Are you under the impression that is good practice?

 

There was an Engineer at work who used to tell me "The only stupid question is the one not asked".

 

So I guess everyone that cleans under the hood with a hose has to replace belts and pulleys all the time right?

Yeah driving underwater can fuck things up, but intermittent water does not. Have you seen the grille on the new Tacomas? The whole engine bay gets wet when you drive in the rain.

You are correct that water is not a good bearing lubricant. But bearing grease (which is) wouldn't be very good if it was soluble in water. It's not. It doesn't wash away easily at all.

 

I can’t say i’ve ever checked my Tacoma but most pulley bearings i’ve seen and used in the last 20+years have been the ‘sealed’ type. Not sure if they’re 100% waterproof but they’re usually pre-lubed, unserviceable and have steel shields with rubber seals so I imagine they’re pretty darn close.

Also, i’ve been using normal, nothing-special, sealed bearings on snowmobiles for 20+years too. They routinely get totally submerged, frozen, beat-on, overloaded and never re-lubed. They still last quite a long time.

I would never try to submerge my Tacoma, but if I did I wouldn’t be too worried about the pulley bearings right away unless they are the open-face type (which I doubt they are)......

 

I've had to replace more than a few boogie wheel bearings. Always fun to see a wheel fly off and pass you on the lake! But I agree those bearings get put through hell and last.

 

The OPs question was about mudding...not water and especially not clean water from a hose used to clean your engine bay.

Mud and muddy water WILL shorten the life span of your pulley bearings, the bearings in your lower coilover mounts (if you have Kings, Icons, etc), and just about anything else that mud works its way into over time if you do it frequently.

Anyone that wheels knows this to be a fact. Pulleys and most bearings aren't hard to change out so it's just a fact of life if that's how you use your truck.

If you don't like it then I'd be thankful that a bad bearing is all it took to convince you that offroading probably isn't the best hobby for you, some people learn much more expensive lessons

 

OP, do you have a manual-trans? And did you step on the clutch or try to change gears while fording water??
(pre-select your gear to cross, and never change gears in water)
if so... thats was the source of the mistake...
LOL thats big "NEVER DO DIS" in off-roading.

 

As someone who has to do an annual pully change on my truck due to them seizing up from mud, yes they will seize up eventually.

Dont believe everything you see on youtube or the internet, they leave out wrenching on it a few months later fixing the parts that failed.

@Spoonman go learn how to build a real wheeler and come back

 

This bearing is not good for mud.


This bearing is good for mud and will survive much much longer. It is also the style used on pulleys in automotive to survive something called the elements!

 

From what I have read in this thread is that pulleys will fail from mud and or water. Now wheel bearings are of a similar design as pulley bearings and lower on the vehicle too. Are they going to seize up instantly from fording through mud hole or a creek? What about the universal joint bearing. What happens to the pulleys when you drive through rain. Does the radiator prevent all that water from getting on the pulleys? How do vehicles stay on the road when they are made so cheaply? I knew I should have bought a Lada!

 

Well, yea kinda. Got stuck. Had to stop hit the locker to get out. But that was only once! Seriously tho... whys that bad?

 

That the part that sucks about mud, parts fail months after you dip them.

 

The grease used in these vehicles has water repellent properties. I am not saying that you should park in water over night ( I have, parked in a lake half way up the engine over night after my front hub exploded going around an obstacle and got stuck. I had zero issue from this.) But going through a creek will not cause damage. Unless you suck it into a driveline component. I have even changed gears in a creek with out issue. Also as my pictures attached above show, the bearings have seals to prevent water penetration.
