Should I be concerned?

I was poking around under my Jeep yesterday and noticed some 'wet spots' in a few areas.

Both front and rear diff. and the rear left shock area has it as you can see in the photos.

Upon wiping my fingers over the wet spots, it didn't feel oily, smell funny or anything like that....

To the best of my knowledge I havent passed through any puddles in the past couple of days.

Anything to be concerned about?
Condensation that hasn't dried up yet??

Anything making it to the garage/driveway pavement while you're parked?

Interesting that the front diff has it on almost all of the bolts. That can't be a hood thing. I would swing it by the dealer and have take a quick look at it just to be safe. Or you could clean it all off and see if it comes back.

It's just some fluid comming through the RTV.my rear differential is doing it too. It's nothing to be worried about unless it's making it to pavement.

Next oil change though, change out your diff fluid. Not the lazy way either. That way a new gasket seal can be installed, and you'll be good to go

2 months old and bad seals already?? It's also on one of the shocks too....what would that be from?

I'll wipe it down tomorrow and see how it looks in a day or so.

Maybe a dealer visit is in order...

Thanks guys!

I don't know what's up with the shock. It's might be from the diff. Clean it off and watch it.

I'm not sure when exactly fluids get added. At the factory, or at the dealership, or what. But if you undo all those bolts there, you'll find it's also sealed with RTV. It might have just been sealed bad in the first place, or a bolt wasn't tightened down quite enough. I don't think the diff cover is cracked or bent or anything, and slight leaks on differentials like this are common.

I'm leaving mine alone for now since I'm lazy. In 1000 miles I will replace the seal when I change out my oil. Since your jeep is new you can tell the dealer. Maybe you'll get a free differential service?

the oil on the shock means the seal is leaking...if enough fluid is lost you'll find the ride deteriorates. I had this and the dealer replaced the shock under warranty

Differentials been leaking for over 100 yrs, some don't--I've never owned one that didn't seap, a little around the bolts

Don't worry about it, check for any increase, then while under warranty, take it in !!

However, shocks can go forever without blowing a seal--Take it to the dealer, before you wipe it off, they may clean it and tell you to drive another 1000 miles, then check, if it leaks more, or rides bouncy--bring back, be sure and get a dealer invoice for the check, even though it'll be free, you'll need mileage and dealer check--PROOF

Good luck

JIMBO
