Front differential seeping fluid?!?!?!?
 
Hello once again.....Crawled under the jeep last night to see how hard the front bumper is to remove and noticed dark area on left side of differential along the bolt pattern. This is where I get the knot is my stomach thinking about if this is oil and how much I am going to have to fight with dealer to get it fixed....

Anyone else had problems with thier differentials leaking or seeping?

How hard do you think it is going to be to get the dealer to repair this?

09 jk with 3000 miles on it, nothing but open highway driving so far......

Let me know your thoughts...:banghead:

I don't believe the dealer will give you any problem fixing your leak. Probably just a loose bolt on the diff. I had a leak by my breather tube. Sprayed gear oil all in my wheel wells. Front Diff was overfilled from the factory. Just drained a bit out and all is well.

AndyLA 05-14-2009 06:09 AM

Yep, heard lots of stories of overfilled diffs...... probably another one.

blekaxe,

Any luck finding the noise yet?

Well, I cleaned up the differnential last night (absolutly no residue left) drove to work this morning and just checked it. The lowest bolt has a small ring forming around it that has an oily feel to it. Trying to decide if i should go to dealer tongiht or drive it another couple days to let the residue really build up and then take it in. Is this a wait type fix or is this a drop off to let the thing cool off?

As for the squeel JK'n I put a microphone near the Tb and you can hear it there. Then i decided to place the microphone in the filter box and you can really here it there. Finally moved the microphone down under the chasis near the transmission and can just barely hear it. At this point i decided it was TB and lost interest. I think it sounds more noteciably now that I have a K&N filter in the stock box.

When you bring it in for the leak if that is what you decide to do, maybe ask them to check the TB too and look for things like a gasket overlap. Might be worth the effort while it is in for the work. I usually hate to give up the use of mine while they have it all day so I try and get as much done as possible while it is in.

Took the jeep to the dealer today to have the leaking differential repaired.... I was surprised they gave me no hassle at all and said yes sir.....

Got it home to take a look and they covered the thing with sealant.....Still looks like 2 bolts are leaking oil though!!!!!:banghead: Figure I will give it a couple days and check it again see fluid accumulating. Then I will take it back for a second time.. Does the gear fluid have an add smell to it or kinda clear sticky color?

Any advice if i have to take it back again?

blekaxe 05-19-2009 10:53 PM

Nothing?

nvr-enough 05-19-2009 11:03 PM

gotta seepage issue huh? sounds like something you should go to the doctor for.....

no but really based on the last few post it may just be over filled. At some point it should stop and be at a good level.

iamagolfspaz 05-20-2009 05:14 AM

If it keeps leaking at the 2 bolts, take it in again and have them fix it correctly. Just may be loose bolts.

Diff fluid smells bad, so no issue there. As for what to get fixed. The correct way to fix it would be to remove the cover, drain the fluid, scrape the old sealer off, reseal,Then torq the bolts to spec and top off with fluid.

blekaxe 05-21-2009 07:56 PM

Well, took it back to the dealer for the second repair today. Any wagers to how long this one will last? The last one made it all of 6 miles home before she started dripping.

iamagolfspaz 05-22-2009 04:46 AM

Hopefully it all will be fixed and no more leakage.

blekaxe 05-27-2009 06:25 AM

Well, it still leaks from one bolt, more like a seap around it. Do i take it back again or should I try lossening the bolt to put some RTV on it to try and get it to seal?

ema 01-22-2010 01:46 AM

I guess it would have been more favorable if you took it back to the dealer for a another repair since they are the one who touched it last. Did they try changing the cover and other stuff?Perhaps what they did was to just prevent the leak and not really look for the source of the leak. Anyhow, I heard Mr Gasket Differential Cover are durable.Were you able to try it?

irideducs 05-21-2011 04:48 PM

I just noticed the same thing on my 2010 JKU with approx. 4k miles. Will try to go in for a fix this week. Mine looks like it is coming out of the gasket area on the bottom -- a few drips on the floor each week.

SeaComms 05-21-2011 07:28 PM

Personally I would ask them how they are going to fix it. With only 4k on the clock their first attempt will most likely be to clean it thoroughly then retorque the bolts - this is pretty normal and could fix the problem.

If it doesnt, it needs to be removed and cleaned thoroughly and new gasket with proper gasket sealant applied or it will simply leak again.

Another issue we have down here is rust - the diffs and covers are covered in surface rust by the time they arrive at our showroom! We have quite a few start to leak due to rust pitting the steel.

They still cover them under warranty for leaks, but I would never fix them properly, just squeeze some goo in there and hope for the best.

I had the same issue on both of my diffs and I only have 5K miles on my Jeep. My jeep is lifted with big tires, bumpers, etc. I too obsessed how much push back dealer will give me, but they never said a word about my rig being suped up. They opened both diffs, changed gaskets and refilled it with new fluid. Now all is good and I am very happy about it. Go to the dealer first, if it is under warranty they have to take care of it for you.

Don't forget that the OP was two years ago. His problem was probably solved by now.
