X2 , it's always risky but I would not go deeper than the intake, unless you have a snorkel, but even then it's risky I'd try avoid it...

 

When the JKs first came out there were some instructional videos on the Jeep.com website and during one of those they mentioned thirty inches of water. However, I think officially it's like only 12" of water. Of course, the amount you can ford is going to vary with lifts/tire size since you're lifting almost all of the components that are affected by water--the diff's being the one exception. That's why you can extend the diffy lines, as previously mentioned.

However, do be aware that the diff's run quite hot and when they hit cold water the first thing they do is suck in stuff as quickly as they can. Most of that comes in through the breather hose. However, it is still possible for some water to be sucked in through the various seals. So, after any deep water run, you should make a quick check of your diffy fluid to make certain it's uncontaminated. While driving Medano Pass Trail in August, we had about a dozen water crossings. Upon return home I had already planned to change the fluids, and the rear axle was contaminated, slightly, by water.

 

How do I do this? Sorry I am new to his kind of stuff. All my cars in the past were small FWD or Camaros and Firebirds

 

Pull the fill plug (NOT the drain plug!). Reach through the hole and dip your finger into the fluid inside. If it comes out oily without any milkiness (even a tiny bit of milkiness), you're good. Be aware that it stinks like all get out.

BTW, my TATA:

 

Have you guys ever considered reading the owner's manual?

Water ingestion into the axles, transmission, transfercase, engine or vehicle interior can occur if youdrive too fast or through too deep of water. Watercan cause permanent damage to engine, drivelineor other vehicle components, and your brakes willbe less effective once wet and/or muddy.

Deep so deep so deep, put her a** to sleep.

 

my 2011 did not come with one

 

Also understand.....that even tho "they" say water 30" deep, a big problem "can" occur if you get into water deep enough to cover the bottom of your radiator fan. If your fan happens to come on while you are in that deep, it can sling water all over the engine compartment AND into your intake. There have been plenty of guys around here that have hydrolocked from far less water than 30".

 

Sounds like a good day
