I've read a lot about people draining the diffs after "swimming", and since here almost all trails have river crossings (1 to 2 feet deep at least at the crossing), I'ms interested to know how to proceed.

 

Thanks a lot Toad... Now, should I worry even if it is just crossing for about 5 seconds?? I mean, there are a loooot of crossings, but side to side, not more than 15 seconds... Should I worry???

 

How deep are the crossings, and how high are your breather tubes?

 

im going to do mine today. i have 17000 on my jk and only have a few crossing nothing to crazyy and nothing for a long time, so ill let u know how dirtyy my diff oil is

 

before I raised my breathers, there was always traces of water contamination in my diffs.. ever since I raised them it has been good........

Doing the diff service is quicker and easier than changing your oil. for a while I was doing it after every trail ride

 

Here is my first front diff oil change at around 4000 miles. Note that this is with 'no' water crossings. Not sure how the water got in, but maybe the high pressure car wash or something? Don't know...


Draining those diffs is quick, easy and cheap, and also let's you check for excessive shavings/sludge/foam/whatever.

 

Most crossings I do are about 1 to 2 feet deep... Mine is a stock 2dr, NO MODS (yet), so the breather tubes are as they came from the factory...

 

Stock, and the crossings are about 1 to 2 feet deep... Still a 2wk-old baby, mods coming soon... BUT, here in Puerto Rico, ALL trails have a looooot of mud, and bogs that are required to cross are at the very least, 1 ft deep, so this is a determining factor... SUGGESTIONS???

 

i went to check my oil in the front diff and as soon as i took out the front plug came out oil came pouring out i tried to aid more to it but it woundnt take it from what i have heard as long as oil is coming out of the top hole u have enought oil in is this true?

 

Yes. Unless you have a lifted Jeep...the holes on the stock covers are designed to let you fill the right amount when the Jeep is stitting level on the stock suspension. If you move the axle away from the frame, you change the angle that the diff is sitting at, meaning that the stock hole won't allow quite as much fluid to stay in the diff.
