Leaking Rear Axle seals ?

Hello gentlemen im new to the site and i had a couple of questions i recently purchased a 03 rubicon which has 62000 miles on it drove it home then drove it on the interstate and engaged the 4wd just to ensure that it worked properly then i went home and parked it well when i went back out ii was walking up behind it and noticed that the inner sidewall of the tire was wet so i crawled under and it seems that my axle seals are leaking so i called the dealership that i purchased it from and asked them what service they did to the jeep whenever they got it for a trade and they said that they replaced the axle seals and axle bearings as i believe them because the caulking looks brand new on the transfer case and i saw the paperwork confirming now my question is could the leaking be caused by overfilling ? or improperly replacing the seal because it didn't leak whenever i test drove the jeep and i took it for a pretty long test drive it just happen outta know where any ideas the dealership has agreed to fix it but im just wondering what would cause this...

Secondly, i've noticed that whenever i start the creep and she is cold that a mild ticking comes from the engine it sounds to me like one of the lifter because after it heats up it stops because if it where a rod it would be ticking all the time.. and i also thought that it might be the exhaust manifold but i was wondering how i could tell without getting tooo in depth with trying to figure out what the cause is im by no means a mechanic... i have been told by two other jeep owners that the 4.0l are just notorious for the ticking when cold.. they both said that running it with that ticking isn't going to hurt it by no means what so every exact words were "Aww she'll be good for atleast another 100k" but they said if i was really worried about it and didn't want to have the engine dismantled that i could try some marvel mystery oil or some hi tech... but i just wanted to ask some people about it before i do the deed.. but if anyone could help out that would be awesome thanks...

The ticking seems to be common on jeeps when they're cold. A little Lucas Oil would probably quiet it. As for your rear axle, you have a Rubicon, so that means you have a Dana 44 rear end. The outer axle seals and a rubber type ring that can wear out or leak if not property installed. You'll need a press to install new seals. It seems the dealer would fix that if you just bought it.

Re eval

Hello just wanted to post a update for the reason they where leaking. I took the jeep back to the jeep dealership. Well apparently whenever they did all the work to the rear end and replaced everything i listed in the post before they used all aftermarket parts IE: Advanced Lotto... and NAPA parts well anyways this time. I told them that i wanted OEM parts from the manufacturer (Mopar I believe) and they replaced them not just the seals but bearings, rings, and seals... Free of charge.. then re-sealed the transfer case with sealant.. They took great care and told me if it leaked anymore bring it back to them and they would handle it..

Also for the ticking they told me that it was probably a lifter like i stated before so they changed the oil (Using a Mopar Filter) added Marvel Mystery Oil and then told me to run it back to Kentucky (where im stationed) and then change the oil again and add half a bottle of Lucas additive which they also provide for me... So hopefully that fixes it but if not i will just run it til something happens

I wish that every stealership had a service department like that dealership does i was very happy with them...

Did their fix solve your ticking? Also, what kind of Lucas oil additive did they recommend? I'm having this issue and if this works I'm gonna try it.

NAPA recommended Lucas Hub Oil for me. They had to grab it from the back. it wasn't on the shelves.
