2014 jkur with 32000 miles I am leaving for the Rubicon Trail in the morning. last evening I took it to the ramp as I put some bigger bump stops in the back and longer rear shocks so I wanted to make sure with all the extra weight I was carrying that I was going to be good. So get on the ramp and check my clearances. I had the passenger side up on the ramp and probably took 10 or 15 minutes checking everything out, probably was on the driver side about the same. I get home and gear oil is dripping off my knuckle and on my rim etc. it was probably about a 1/2 shot glass full maybe a bit less. But you know how oil looks bad regardless. I can tell it had run out the end of the axle tube. I was like wtf. I check under my rig every other day and always bond dry. I had not ever changed front diff oil so I pull the fill plug and oil comes gushing out so I know it was over filled. It almost seemed like I had some pressure the way it came out so I check the vent and it is clear and breathing freely both in and out. I clean it up good with brake cleaner and compressed air. I did change the oil and filled it to the bottom of the fill hole. Took about a quart is all parked on level cement floor. Looks like about 1.3 or so quarts came out.

I drive it about 40 miles to see if the leak is going to be a gusher and so far there is not no seepage coming from behind the plastic dilly bob. So my question I have about 2000 mile round trip to the rubicon and back do these ever go full bore leak in that amount of driving. Is it possible that the seal is still good just the angle that it was at for 10-15minutes was enough for the oil to run past the seal? There was absolutely no sign of leakage prior to this as I checked my brake pads and added a spacer up front in the last couple of days and every thing was dry as a bone.

 

You know the oil level is adequate. If you don't see any more leakage, I wouldn't worry about it. Clean off all the residue with brake cleaner and keep an eye on it.

 

I went a year before I finally got the ambition to finally change my leaking seal. The thought of the hassle for a $12 seal sucked so bad, I blew $500 to install Ten Factory shafts while I had it apart. It's not going to all of a sudden let go, you'll be fine for your trip.

 

well within 500 miles the other side seal started spewing oil. Made a hell of a mess over the 2000 miles but a little oil goes a long ways. I got back yesterday and took it to the dealer to day and very first words out of his mouth were "it's lifted" 34,000 miles on it today was under 32000 when it started. He then asked if it had been regeared and I said no and that the diff had never been opened and I told him when I pulled the fill plug oil poured out so it has been over filled from the factory. They had to order seals and they are a week out. He said he had not seen a JK with leaking seals before.

 

If the dealer gives you crap I heard about the Magnuson-Moss Warranty Act and it covering you putting aftermarket parts on, as long as those parts didn't relate to the direct failure of what needs to be replaced under warranty. I still have to do some reading on it so don't quote me.

Just did a quick google search. Copy and pasted below


In a Consumer Alert issued by the Federal Trade Commission (FTC), the agency confirmed that “The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part.” The alert outlines key provisions in the law that provides protections to car owners. As defined by the FTC, an “aftermarket' part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer.”

“The FTC’s reference to aftermarket parts is equally applicable to specialty parts,” said Russ Deane, SEMA’s General Counsel. “Under the Magnuson-Moss Warranty Act, the warranty cannot be conditioned to a specific brand of parts, services or vehicle modifications unless those parts or services are provided free of charge.”

The alert notes that a consumer has the right to patronize independent retail stores and repair shops for parts and service without fear of voiding the new car warranty. The dealer/vehicle manufacturer has the right to deny a warranty repair but they must demonstrate that the aftermarket part caused the problem. The warranty remains in effect for all other covered parts.

The FTC alert may be downloaded using this link: http://www.ftc.gov/bcp/edu/pubs/cons...ts/alt192.shtm.

The alert was issued in response to an FTC complaint filed last August by the Automotive Aftermarket Industry Association (AAIA), Automotive Oil Change Association (AOCA) and the Tire Industry Association (TIA).

 

the mm act is not worth a crap. you have to prove the lift and big tires did not cause the problem not the other way around. sure big tires wont break your radio but they can say they caused your tranny to go out. The mm act was designed so you could use say champion spark plugs instead of motorcraft or say a wix air filter instead of a mopar air filter etc.

 

The dealer said he's never seen this before? Must first day on the job...

Mine dribbled on and off for a year. Clean it off with break cleaner nothing for days sometimes weeks, then a little bit. Worse in warmer weather then cold.

About as annoying as runny nose. Just had both replaced.....for the second time

 

Mine's been leaking for a while now. Getting sick of smelling gear oil and cleaning it off my new garage floor when I forget to throw a rag down. Since I have to tear it all apart anyway, I'm using it as an excuse to do sleeves, gussets, ball joints and one of the ujoints is binding a little so I'll swap those too.

 

^good point, might as well doing most of the same steps for BJ and y joints. Did my u joints at same time as seals.

 

The dealer/vehicle manufacturer has the right to deny a warranty repair but they must demonstrate that the aftermarket part caused the problem. The warranty remains in effect for all other covered parts.

So no I won't have to prove the lift and tires did not cause the problem, they have to prove it caused direct failure of it. Understand a tranny, but were talking about an axle seal guy.
