The general rule of thumb, which I don't myself follow is to change your diff fluids if they're submerged in water. If you have water in your airbox its time to seriously consider buying a snorkel. Changing diff fluid is very very easy to do and takes probably 20min. Good thing to have regularly maintained IMHO

If I have submerged the Jeep multiple times on an outing, or if it were for an extended period, I generally like to change the diff fluid. AS said above, it is a very simple process, takes very little effort, and is a great way to ensure that the fluids are in fact fine. To change your engine and diff oil (while they may not be necessary) is simple and cheap enough. I would say go ahead and service the vehicle, make yourself feel better, and Jeep on!

Hot differential enters cold water. Diff cools suddenly. Negative pressure created in diff housing. Breather is supposed to allow air in to balance pressure.

Now lets say, however some cold water gets sucked into leaks around the diff cover, breather tube connection, tube and pinion seals. Bearings, rings and pinion now exposed to oil-water emulsion. Oil properties change, internal parts rust and wear due to presence of water. Even worse when your breather is submerged or if it happens to be blocked.

Doing water crossings? My advice is to buy a 5-gallon pail of 80W90 dino and change diff fluid often. Reason why they say to change diff oil so rarely in the manual is because it is written for 99.9% of the "other" people who stick to the roads. If the water was deep, this can also apply to your engine and transmission, too! Happy crossings!

Will i have to completely pull off the diff cover or can i just unscrew the bottom drain plug. Both ways will drain the diff however only going the plug route will save me money by note having to buy new gaskets and silicone.

I've changed mine twice and have just used the drain plug and fill plugs. I'm sure eventually I'll want to pull off the cover, but with regular changes I don't feel as tho that'll be for some time. Unless of course I drown my jeep....

I found my breathers. The front axle one is right below my driver shock tower. My rear axle one was between my muffler and wheel well on the passenger side. I'm defiantly changing the fluid since all the breather is a plastic hat basically at the end of the tube. I know for a fact I got water in my axles.

The transfer case breather is way up behind the heatshield.

Two more questions, if i tie all the breather together and route the single line higher do i have to worry about cross contamination between the diff and transfer case fluids and if i do redo the breather setup this way will i have to worry about changing my fluids after offroading.

Always change your diff fluid after submerging in water. Open it up and take a look anyhow

If it looks like chocolate milk...change it.

Is this even if i do relocate my breathers into my air intake box and get a snorkel?


Changed it today. Everything seemed fine the oil still looked like oil and didnt seem to have any dirt, some metal dust on the drain plugs but nothing to worry about.

Even if you tie the breather lines to the airbox you still should replace the diff fluid about every 15k miles if you put the rig through water. As for cross contamination, unless you over fill or submerge the breathers under water often, you won't have to worry about it.

Another thing. I put full synthetic gear oil in both diffs. I was looking online and there was no definite answer about this. Running full synthetic doesn't matter as long as i don't go back to regular gear oil anytime down the road, correct.
