I say there ain't no black and white. Common sense goes a long way when maintaining any vehicle.

I had an old Bronco that was pretty well worn out when I got it. I wanted to use it for rougher riding than my nicer 4x4s so I didn't have to worry about hurting it. The first thing I did was replace all of the seals that even pretended to leak oil. If oil gets out, water can get in. Most seals are designed to do a better job of keeping contaminates out than oil in, so if they're leaking oil they still may keep water out. I replaced the seals so I wouldn't have to worry about changing fluids after water events. One seal change is cheaper than a bunch of fluid changes - and eaiser in the long run.

Generally, the amount of *time* you spend under water and how dirty the water is has the biggest impact on damage. Oil and air are lighter than water and try to get out and up when an axle or tranny or engine is submerged - first the air bubbles out, then the oil. If what replaces the air and oil is dirty water you'll have grit causing abraision damage between any two moving surfaces. Water itself ruins bearing surfaces even if it's clean. Same problem with your altenator. The best remedy if water enters lubricated parts is to replace the lubrication. Just draining and refilling may not be enough. For example, if you have water in your diff and drian the old fluid, water may still be hiding in the bearings at the shafts or pinion. Better clean it all out with something under pressure such as carb cleaner or WD-40, then dry completed with air. Now refill with fresh fluid.

For electrical stuff, water is a conductor. If water was in those components while they were on, you may have damage from shorting. Long term it may cause rust and corroding and leave behind minerals that will do damage long term. Once again, you need to clean it under pressure and dry completely. Try not to turn anything on unless you really need to until you get it cleaned up.

As for whether to get 'em dirty or not... my new Wrangler has less than 1000 miles on it and has already been deep in the mud. I bought it for 4-wheeling. Even though it is new, it is not my daily driver, and I only live 2 miles from work, so if I break it I can still get to work. I get not trashing your Jeep if it is all you have. I also get that any machine used hard, but properly maintained usually lasts longer than one babied and not maintained. It's generally not how you use them, it's how you care for them.

That's my twenty cents...

Good luck!

Water won't hurt the clutch, if you let it slip alot you might burn it a bit but that's a function of your driving.
You shouldn't get water in your tranny if it's sealed properly but even if you do it won't do immediate damage, if you find signs of water contamination then change your fluids.
I don't understand what you mean by "makes your Jeeps have all kinds of noises"? what noises will water cause?
Yes, water can hydrolock an engine, most of the time the engine will stall before you do any real damage unless you completely submerge your air intake. Somewhere around here I've got a picture of my old Jeep Gladiator swamped halfway up the seats in a pond, complete hydrolock, I spent about an hour working on it but finally got it running and drove out, That was about the 5th time I'd done it without damage.
Man I wish I could find that picture, I loved that old truck.

A lot of this can be attributed to getting dirt in your suspension bushings, usually polyurethane will squeak when you fill it with dirt.

And clutches will fail completely if water is sucked into the vent (stepping on the pedal when in deep water). I have towed several Jeeps off the trail after they got stuck in deep water and instictively stepped on the clutch pedal.

well i know now for sure that i will never go in deep water again...not unless there is a ton of room for someone to winch me out and there is a very easy exit out of the creek.

i went down in a creek yesterday and couldn't make it back up the entrance...never again...there was another easy entrance but a pipe that goes across the creek blocked the way so never again will i do that unless i am positive that there is an easy way that i can make. ooooh, i hate water right now...it was fun riding in the creek until that happened.

Fail as in come apart/destroy themselves? or fail as in slip till they dry out some?

Has anyone evermanaged to get thick muddy water through the vent on top of your hood near the window, and the turned your air on and had thick sludge drain through the fan above the passenger floorboard? I think I might have to replace it casue it don't even work now and the mud I was in was only halfway up my tires.

I'm assuming that since your jeep was wet for 3.5 hours in that pond that it was not running the entire time. Chances are you have water into your catalytic. They don't like water, just like any other cat. The materials inside tend to break down/fall apart once exposed to water like that. If your cat starts rattling and/or you throw an emissions code, chances are you'll be replacing the cat.

You may also want to consider extending your breather/vent tubes from your transmissions and t-case if you can - preferably up into the engine area by the firewall. That will help prevent water from getting in there in the future.

You may also want to consider securing some of your electronics to better resist water by sealing up the connections where possible after applying dilectric grease to keep water away.

Jeeps can handle water, but you really want to be prepared for it. Even on the trail, if you have no intention of going through deep water or mud, you can come up on a hole that you really don't have a choice to avoid. A friend of mine went through this:



and did just fine as she didn't stop the engine. But her vent lines were too short and fluid needed to be changed. Everything is fine - but dirty.

how do you extend the vent tubes from the transmissons and t-case. as far as the dilectric grease, can i just pop open the connectors and smear some in. can i do this on all the connectors?

Extending the vent tubes should be as easy as finding some tubing from a place like HD or an auto part store that fits the vent holes, using a clamp to attach it, then run it up someplace higher.

Your idea on the grease sounds correct. You should be able to do it on the electrical connectors, but don't be sloppy about it.

I know there is a writeup on sealing up the connectors and making them handle water better, but for the life of me can't find it.
