Going through water in my Jeep?

I already asked a question about this kinda but my Dad brought something up that I never knew. I know I should extend the breather lines past the door level (because as deep of water I go in is about that level maybe a few inches higher) but do I need to buy extensions for them or are they long enough for me to do that?

Here is what I didn't know. Apparently water can also go into the differentials too, so my question is, A. How easy is it to drain them and how long would it take and B. How often should I do this? I don't really go offroading all that often either.

Also if there is anything else I should know that would be great to tell me now!

The breather lines for your diffs are as follows. Front is up by the radiator. Rear is up by the gas fill tube. You should change the lube every time you're in deep enough to submerge the diffs. There have been write ups on how to extend the breather tube on the auto. Here's a write up for the diff lube change off Stu's site http://www.stu-offroad.com/misc/diff-1.htm

Where is the water coming to on your door? Bottom of the door sill or the top by the windows? If it is just coming to the bottom of the door sill, you will not need to extend the axle breather tubes. However as said, you should change your diff fluid every time you go through high water for long periods of time.

its at the bottom basically, there just deep water puddles, sometimes I will go through them fast, other times I take my time but they aren't very long at all, maybe 10-15 yards at the longest.

Careful of your trans too, autos don't take well to getting water in them.

Anything I should do to protect the transmission? Or should I just avoid water alltogether....

since he has a 2004 the breather tube will be up high enough to the point where he won't have to worry about getting water in it. The relocated the 42rle trans vent tube for that reason. The 32rh OTOH is a different story.

anyhoo, just a recap, so my breather lines should be fine for what Im going for, but I should change the oil in my differentials after every time I go in deep water for a long time or deep water in general? (I puddle jump, not cross long deep rivers haha). Also is there a way to water proof my differentials? And you guys are saying I should watch out for my auto trans. too. Is there a way to water-proof that or is it high up enough where it shouldn't matter?


Thanks for the help!

Here is what I do about every month. I have never had any problem with my diffs but I make sure to change the fluid every time I go out, I have never had milky fluid. If you don't want to have to crack the diff seal every time you can pump the fluid out although cracking the cover off allows you to check for metal fillings and gear wear, I crack it every time. As for the auto trans I am not sure, I have a manual although I avoid shifting while in water at all costs unless I get stuck.

Whenever I hit deep water I check the diff fluid when I get back home. I just remove the fill plug and dip my finger in there. If the fluid is still clean, you have nothing to worry about and don't need a change. You'll know when you get water in the diffs. The gear oil will become a whitish milky/milk shake type color. That would mean it's time for a change. Water's only gotten in my diffs because of a leaky axle shaft seal which will let water in, or when my breather tube fell off and was floating in the water sucking everything in

I know we already went over this but now that I'm starting to find new places to wheel, I just have one last question about this (I swear it is!): what would you say is the deepest water I can go through before stuff starts to break or require major work? Also would a air intake bag from K&N be good enough for keeping water out of my air intake as long as it's not submerged?

1. You do not want to submerge you're fan or It'll suck itself into the radiator.
2. The trans. vent line ends right at the top of the trans., drivers side, by the fire wall. (I have a 42rle also) I extended mine to the top of the firewall to be extra safe.

Well I finially took that class I was telling everyone about! But I didn't learn too much on offroading or about the vehicle in general but I still learned good stuff (it was only 7 days but two of them was taking apart a diesel down to the block and putting it back together). Anyways one thing I did learn is that apparently this is a problem on the humvees too, but when they hit water fast while the fan clutch is on, thats what causes them to break (same thing that happened to me I guess even though I wasn't going that fast). Anyways if the fan clutch is off, you generally don't have a problem.

So at what temp. does the fan clutch turn on? I figure if I only go through water when it doesn't hit that temp, I should be fine in that respect.
