I do change out the oil (actually all fluids) more often than recommend by Chrysler due to wheeling.

And the deal with water & mud then changing your fluid is because if the fluid & internals are real hot then submerged under water, the rapid cooling effect makes the pressure drop on the inside causing a vacuum type effect. And this vacuum can draw water into the housing thru axle seals or pinion seals. To check it, take the fill plug off & stick your finger in & see if the oil looks liek it has water in it. If you've been doing like a whole weekend of wheeling in deep mud & water for long periods of time, I would change it for peace of mind.

and if you don't have your window sticker, you can go to the jeep website, and up in the top right hand corner there is a drop menu titled "owners"
set up an account (it's free) and type in your vin #, and you can access your build sheet, everything that was put into your particular wrangler when it left the factory floor.
if worse comes to worst, you can always pop your rear diff cover off and take a look-see

|Ridge Rider||Rguy01, I believe it is an option. Do you have your window sticker spec sheet, it will tell you. Mine is a 2010 but it was a option I choose.|

|rguy01||Can someone answer the question on whether or not a stock 2011 wrangler has a limited slip diff or not?|

AMSOIL the worst in the business eh?
How about some Penzoil 10W40 in the engine too. They have race cars in their commercials so that will make it last.
My RR wheel bearing went out after 18K (warantee) & the dealer was nice enough to not change the diff fluid while recommending their $250 diff treatment "package." Thanks LHM. High quality warantee work. Anyone ever hear of changing a wheel bearing & not changing the fluid / repacking? Maybe I'll try running a bearing right out of the box without greasing on my next brake job. That should do the trick. Oh yeah, & the dealer said that the front diff fluid had to be changed at the same time & my nice red p/s fluid needed to be changed too (service interval anyone). Interesting that the chalk mark on the oil fill & drain were still there on the front diff. Hmmmmm. I had no idea that I resembled a 16 year old little girl driving daddy's Jeep. My hairline would tend to disagree.
So I immediately went down to the local Amsoil outlet & picked up some 75 140 (since I tow occasionally) with the additive. I did it myself for about $80 the following day when their "membership" was included. (front was still nice & clean too btw but somehow I could not get the chalk marks to line back up perfectly)
That specific weight fluid has to be changed a little more frequently but is better under towing conditions.
Amsoil sucks , Oil membership
Not changing fluid with a fried bearing

|somis||I just did some research on this Amsoil topic, and everyone from Corvette guys with LS3's to rally racers, many people swear by their product and recommend it over Royal Purple. Personally I'll run Mobil 1 synthetic because its readily available at my Napa, but I would like to support Amsoil because they are a smaller company and have put on many motocross events.|
|04-16-2013 03:28 AM|
|somis||Yea I have a hard time believing that Amsoil is not a quality product. I know they make quality products motocross and street bikes, I dont understand how a company of that stature wouldnt keep up their R&D program to compete in the auto industry|
|04-16-2013 02:04 AM|
Do you have any credible citations to back those statements up?
|04-16-2013 12:57 AM|

|legitposter||Whatever you do don't use Amsoil. It's old school and not made for today's tight tolerance components. Even engines can have their warranties void if amsoil is used.|

|river2c||The 85W-90 is conventional gear oil. The 75W-90 and 75W-140 are synthetic gear oils. Any of them will work fine in the JK differentials (clutch-type limited slips require synthetic gear oil or a LS additive to the conventional oil).|
|04-16-2013 12:13 AM|
|joe002||If you don't tow then 75w90 is good.|

|NFRs2000NYC||Whats the correct fluid for a 2012 sahara? The manual I think states 85-90 but the pics above show 75-90. Any advice?|

|rguy01||Do stock JK's have limited slip differentials? I was watching a youtube video and it said to check if you do, because you might need to add an additive for it.|

|MercMan||Did it yesterday for the first time myself. Very easy and used about 3 litres total. 2 in the back and 1 in the front. This stuff. I notice the pic I posted says for motorcycles etc. Not sure if there is a difference but make sure you buy the right stuff. I know I used HYPOY C for mine.|
|04-15-2013 07:11 PM|
|rguy01||Does anybody know what type of fluid it takes?|

|wrangler0||From what I've read, there's nothing to grease on a stock jeep. No zerks.|
|04-15-2013 09:29 AM|
|Raziel||As a safety after going through deep water, they recommends changing the fluids in case it does have water. It should look milky, but you probably should change it regardless of how it looks to be on the safe side. $10s of dollors for fluids is better than a while new drive system!|
|04-14-2013 10:51 PM|
Also, what all parts do I need to grease, and what grease would you recommend?
|04-14-2013 10:47 PM|
You only need to change diff fluid at recommended intervals or unless you have water in them- the oil would be milky.
I grease fittings every oil change for longevity. :thumbs:

Changing Diff Fluid and Greasing
Hi, I have a 2011 Wrangler sport. I went mudding recently and have read that you should change your diff fluid and grease up your jeep after. Im new to jeeps so I dont know much. What fluid do I put in the diff's, and what type of grease should I use. I have youtubed how to change the diff fluid and it looks pretty simple. Although, I am wondering what parts I need to grease.
