Hey Friends,

I left my Rubicon 2.0L Turbo Unlimited in the garage for a month while I went on vacation up north (I know, I know). When I came home I discovered a slippery fluid under the front differential (see attached). Anybody know what this is from or has it happened to you?

If the fluid has the distinctive scent of gear oil, then I'd check the bolts on the differential cover. Provided they're all properly snug, a new gasket may be in order; this is possibly a warranty item through your dealer.

Definitely take it in to the dealer. Could be a leaking seal at the front driveshaft. Or bad gasket on the diff cover. Either way, not right...

Thanks James! I have an appointment at the dealership tomorrow. The funny thing about this is it hasn't leaked since I've been back now for about a week.

If you drove since you have been back, the diff heated up normally and the seal swelled as it naturally does.

I would make sure you show them the pictures so you don't get a "can't replicate complaint"
Thanks for the feedback Matt! I took it into the dealer this morning and they just replaced the front diff seal because it's still under warranty.

Hey Aaron, I seen you live in Perrysburg, OH. I used to live in Toledo and my sister was a Maumee police officer.

It looks like a shart. At least how I imagine a shart would look, I wouldn't know from first hand experience of course.

It might have been "JL tears" showing how much it missed you! It's important to bond with your ride man!

OK Jeepsters,

Here's the update to my front differential leak issue... I took my Rubicon into the dealer last week 8/25/2021 and they replaced the front differential cover gasket. Fast forward 5 days and it (or some other component) is leaking in the same spot AGAIN!

Additional things that bother me are as follows:

1.) They used red gasket sealant that stands out like a sore thumb.
2.) The service person left a nice red hand print on the diff cover.
3.) If you look at any Mopar/Jeep publication that shows a picture of the front differential cover it looks smooth, shiny new and spotless. My differential cover looks like somebody poured paint down the front (See attached). Where is the quality and customer care?

Note: It was parked in slightly different spots.
