water crossing

i guys i decided to take my jku offroad for the first time this weekend and i found some water. the deepest i went was to the bottom of the front fenders. at that depth is there anything to worry about. i know you guys sometimes talk about changing fluids and stuff and i'm hoping i don't have to do that every time i get in some water. i live in florida so a lot of my off road driving will be through wet marsh. also i have some creeking from the front right when turning sharply either way but it is a new lift so i don't know if something could be loose or if things need to be re greased or just an extra good cleaning. i have a 3.5 RE lift that uses the factory arms so i don't think i have grease fittings but i might in the track bar or something.

Couple of things, first, jeep claims 30" fording (if you go slow), so as long as it is a little under the top of your tire you 'should' be alright. It might be worth extending your breather tubes.

Second, manual or automatic? With a stick, you shouldn't shift when in water. You can introduce crap into the clutch assembly which is bad. Auto you should be fine.

Third, changing your diff fluid is pretty easy, so is pretty simple preventative maintenance if you're concerned at all

it is manual which makes shifting sometimes necessary because idle is too fast when you don't know if it's going to become deeper in front of you. is there a way to make sure it is clean? like get in there and clean it off?

if i'm concerned that it'll be deep, especially if off road, i'll drop into 4lo. keeps you going a little slower, and if you stall, or have to turn the motor off, you can start without having to push in the clutch.

not sure if there's a way to check any of the pieces easily, but if it's working, the clutch is probably fine.

I think there's an inspection plate you can remove to check could be wrong though. To avoid shifting use 4lo that way you have tons of torque and usually no need to shift. I usually use second gear so you have decent wheel speed if you need to start chewing, 1st is a little too low and slow and better for rocks or hills. If you play lots in water I'd recommend a snorkel you never know where there might be a deep spot hiding.

i would but i'm not a huge fan of the look and i just got a cold air intake and the exhaust. i know people say it doesn't help with power but it actually did a lot. it made the bigger tires not noticable.

if you search for breather tubes, you should find it pretty easily. basically, there are vents for the axles, diff, etc, that all end about the top of the fender. you can extend those so you don't get water into those components. there are a couple of writeups floating around about how to do it.

i'd guess the squeaking is from the new lift.

First off, get some Rock Rails on that thing

Great lookin Jeep... if it was at the front fender after the lift and you have not extended your breathers yet I would def. change the diff fluid....also if you are going to be fording water you will want to extend them.. it is really easy, all u need is some 5/16 tubing, some hose menders and clamps.

I did mine for about $30 in parts. took about an hour for all of them... I extended the rear diff behind the rear tail light and the front up into the engine bay by the abs unit.... The transfer case breather is already in the engine bay. only one I would be worried about is the tranny breather which I believe is under the shift boot on a manual. Dont know about the auto tranny.....

Don't forget that the undercarraige of Jeeps are not waterproof, electrical connections wires etc... so no matter how high you extend breathers you can still run into problems.

On the lift have you done anything to correct the geometry of the drivetrain??

Don't forget to extend the intake. Get a snorkel. If your motor sucks up H2O she'll blow!

I have had mine just even with the top of the fenders in water not too long though and checked the fluids a couple days later and it was fine but if I made that a more frequent thing I would deff extend the tubes and may add a snorkel love the way they look but I cringe at the thought of cutting my hood. and it's always best to let someone else GO FIRST he he he he .

some of you guys are saying check the diff fluid? how do i do that? i can't do anything that requires a lift because i don't have that. and thanks for liking my jeep but no rock rails i have amp power steps.

and it was the bottoms of the fenders do you mean the top? i've seen videos online of factory jeeps crossing water deeper than the bottom of the fenders for them and they seem ok but of course idk whether or not they had problems after.

sorry about all of the posting but what would the signs be of water getting into any of the possible areas and what are all of the different areas?

Pretty easy to check if water got into your diffs. Use a normal ratchet without any socket; the head is square and 3/8", and fits into the upper fill hole plug on each differential plate. Take the plug out; you'll probably have oil flow out as (at least on mine) they overfill the differential. Catch some of the oil in a glass. If it is at all milky in appearance, then you picked up water. If it is just dark like normal used motor oil, you're probably ok. Don't worry about the oil that flows out; you don't have to replace any more than to the lower level of the plug. If no oil flows out of the plug, stick a screwdriver into the hole (like a dip stick) and look at the oil on the blade; again, milky is bad but dark is ok

Yes, of course; they both have breather tubes. Same process for both. And both breather tubes can be extended if water crossings are in your jeeping future.
