Leaking front axle/wheel seal

I inherited a '13 2-door Sport from my dad and only recently put some miles on it. I'm pretty new to the hobby. I used 4WD Sunday and afterward started noticing a burnt brake smell. I've had a stuck caliper on the Silverado before so my mind automatically went there. But I turned the steering wheel all the way out and I can see what I call the spindle has had something leak fluid on it. My guess from the way it looks is the outer seal has leaked. The brake line is clean and the brakes are clean.

My question is this: Will I harm the Jeep by driving it on highway in 2WD only? Or do I need to get it fixed before putting any more miles on it?

Thanks.

FIRST: YOU SHOULD ALWAYS BE DRIVING ON ROAD IN 2WD. 4WD IS OFF ROAD ONLY!!!!!
YOU WILL HARM THE JEEP DRIVING ON THE HIGHWAY IN 4WD


^ DID I MAKE THAT BOLD ENOUGH? I'm going to beat up on you here, not being mean, just being real. You need to read your owner's manual.



Ok, now for your question.
The front axle has inner seals, the rear has outer seals. IMO check the fluid level. If the level is OK then you're OK, just keep an eye on it. Never hurts to swap out the fluid, and it's an easy job. Replace the seals if they're leaking.

That said, also make sure it's not dripping down from the PS box.

Yes, I understand that I can't be in 4WD on the highway. I own a 4WD Silverado as well. I was just sorta thinking the use of the 4WD off-road was what caused the leak to be noticeable. I will check the PS too. Thanks for the suggestion.

the front axle seals fall under the 5/10000 valve train warranty. If this applies it is a no brainer to have them replace them. I had to have 2 sets replaced on my 14 jkur one set at 36000 miles and the next at about 46000 miles it is a common problem and has nothing to do with going in 4wd. a little gear oil always looks like a lot so I doubt you have to worry about running dry.

That's funny because I'm right at 36K miles right now. Thanks, I'll get it to the dealer one of these days.

You should be good then. Definitely have them do it because it is a PITA to do it yourself.

They also went to a new design in 2014(think that is the year) that is supposed to greatly reduce the leaks. My '14 had the old style(guess the axle was older). After I screwed up the first set of replacements, it now has the new two pc style seal.

BTW, mine was under warranty but I had it all apart to do gears so decided to replace the seals while I was in there.
