Hello. So I went Wheeling last night and came home. Nothing out the ordinary has been going on with it today. I crawled under to clean it and I have something hanging from my axle. Looks like a rubber seal or something. I don't have a picture of it but this is someone else's in the exact spot and to me is the same thing.

Anything I need to worry about or do to this? Mine is split in half at the middle and hangs like this on both sides. It's between the axle and the dif cover I believe.

If it just RTV (rubber between the diff and cover) then just cut it off if it not leaking.

Personally though, if you have never had your diff cover off to change the oil it might be worth doing very soon. It the RTV is getting old enough to come out it probably due. Plus its a good opportunity to check over your ring and spyder gears too.

X2...at minimum, I would check your dif level.

In my opinion, it appears to be leaking. The wet areas on the diff seem consistent with where the seal/gasket should be....... even if it doesnt leak when. Stationary, the pressure when in motion could be causing a seep, for now. Watch that. A repair could get pricey REALLY quick if you ignore it.

So what do I do to it? Just pull it off and replace it? What exactly am I looking to get to do this?

Very easy thing to do if you can operated basic hand tools. Take your time follow the instructions the other members have linked in this thread and you'll be fine. It's what owning a jeep is about. No need to have a mechanic do it.
Wasn't gonna have one do it anyways. Just I'm 17 and want to know what I'm tackling before hand. Managed to do a clutch and slave/master cylinder system already so this seems to be easy.

Read through the how-to links above. Its a really good thing to know how to do yourself and its not that hard. Don't let it intimidate ya. :thumb:

Think of WranglerForum as a chance to learn...well here is your opportunity to learn how to do a diff fluid change. ;)

An alternative to RTV are these nifty (pricey) seals: http://www.amazon.com/gp/aw/d/B008RACMHE/ref=redir_mdp_mobile/179-1094614-4380757
I have used one in my 30 and 44, pull the covers regularly, and never have a leak, seep, or any problems. There's no waiting for the sealant to cure, no oozing out around the bolt holes, etc. I hate leaks on my cement, and these things work fantastically. However, you can buy a lot of UltraBlack for the same price. But for convenience, you can't beat the Lube Lockers.
