I got my jeep all muddy today driving on some trails. What should I check under the jeep to make sure she is all good after an off road adventure? Also what is the maximum depth of water you can go through? There was some pools of water in ruts and I want to make sure I didn't put her in too much. Anything I should check after that as well?

Congrats on getting the new Jeep dirty. First, I would take her to a good power wash station and spend enough time to properly clean all the mud from every spot you can see on and under your Jeep. Open your hood if you haven't already done so and check your filter and intake. It sounds like you drove it home so the worst that could have happen (hydrolocking) did not take place. Next get the mud off the engine as soon as possible as some or most of it may already be heated onto it. The truth is that once you get it muddy it will never be clean again but you can get a lot of it off. Try a good engine cleaner like Purple Power or Simple Green. Spray it on and let it sit for a few minutes before cleaning off. Remember to not spray water into your intake or heavily blast any electronics.

As far as maximum depth goes, I would always err on the side of caution as you can quickly misjudge a water's level and find your self really in trouble. My rule of thumbs is NEVER go into water/mud that you don't know how deep it is or what's underneath. Second, your intake is just to the left behind your front left upper headlight. That would be the max depth but I would stay clear of reaching it at all possible.

Check the oil in the differentials, make sure it's not too dark....that's the advise I was given on here after my first trek through water.

As far as how deep you can go....as long as you didn't hydrolock, you didnt go too deep! :)

Thanks for the quick replies guys. I believe the depth wasn't more than a foot at worst but just figured I'd check. I tend to avoid water as much as possible but it was impossible on this trail. I've seen where the intake is and also have seen the video of that one jeep that goes into water too fast and hydrolocks the engine before she even gets out. I am however slightly worried as to what I've heard people call what I think are vents on the axles. Where are these located so I can see if any mud, or water got in there?

Going through even a small amount of water to fast can spray a lot of water upwards flooding the engine bay. Never use speed to go through mud or water. Common sense and the ability to keep your Jeep moving while under control and using the right gears makes the difference. Not sure about checking the axles for mud? I'll wait to see what others add.

Your axles, transaxle, and transmission all have breather lines on them. It isn't real easy for water to get in through these breather lines as long as you don't stop in the water but it is still possible. If you plan on going through water much I suggest you get a extension line to run those breather hose up high. Just look up Bob's Smilin' hose extension if you want to go that route.

If you run through the water too fast you can splash water up into the air intake and cause a hydrolock, but you would know you did that very quickly. So drive slowly through the water and you will be fine there. You suppose to be able to go to 30" if done correctly but that really runs risk of breather lines getting water in them and electrical wires gettin water soaked.

Driving Through Water​
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly and
avoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. Shift
into 1st gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L (Low)
position and proceed very slowly with a constant slow
speed {3 to 5 mph (5 to 8 km/h) maximum} and light
throttle. Keep the vehicle moving; do not try to accelerate
through the crossing. After crossing any water higher
than the bottom of the axle differentials, you should
inspect all of the vehicle fluids for signs of water ingestion.​

•​
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you
drive too fast or through too deep of water. Water
can cause permanent damage to engine, driveline
or other vehicle components, and your brakes will
be less effective once wet and/or muddy.

•​
This vehicle is capable of crossing through water
at a depth of 30 inches (76 cm) at speeds no greater
than 5 mph (8 km/h). Water ingestion can occur

causing damage to your vehicle

Before You Cross Any Type of Water
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick.
You need to be sure of its depth, approach angle, current
and bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure you will not
be intruding on any wildlife, and you can recover the
vehicle if necessary. The key to a safe crossing is the water
depth, current and bottom conditions. On soft bottoms,
the vehicle will sink in, effectively increasing the water
level on the vehicle. Be sure to consider this when determining
the depth and the ability to safely cross.
Crossing Puddles, Pools, Flooded Areas or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water
holes are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier
vehicle recovery. If you are able to determine you can
safely cross, than proceed using the low and slow​
method.

CAUTION!​
Muddy waters can reduce the cooling system effectiveness
by depositing debris onto the radiator.
Crossing Ditches, Streams, Shallow Rivers or
Other Flowing Water​
Flowing water can be extremely dangerous. Never attempt
to cross a fast running stream or river even in
shallow water. Fast moving water can easily push your
vehicle downstream, sweeping it out of control. Even in
very shallow water, a high current can still wash the dirt
out from around your tires putting you and your vehicle
in jeopardy. There is still a high risk of personal injury
and vehicle damage with slower water currents in depths
greater than the vehicle’s running ground clearance. You
should never attempt to cross flowing water which is
deeper than the vehicle’s running ground clearance. Even
the slowest current can push the heaviest vehicle downstream
and out of control if the water is deep enough to
push on the large surface area of the vehicle’s body.
Before you proceed, determine the speed of the current,
the water’s depth, approach angle, bottom condition and
if there are any obstacles. Then cross at an angle heading
slightly upstream using the low and slow technique.​
WARNING!​
Never drive through fast moving deep water. It can
push your vehicle downstream, sweeping it out of
control. This could put you and your passengers at
risk of injury or drowning.​
