So I changed my rear diff fluid following the 500 mile break in period of new gears. I put in 2 quarts 75w90 gear oil (Dana 44 w/ Trutrac) and swapped the stock diff cover for an aftermarket aluminum cover. Didn’t notice any leaking from drums. For some reason, I thought it would be a good idea to add another 300mL thinking since it’s a bigger diff cover it could use slightly more oil to compensate (overthinking it. But I didn’t overfill the front diff at all). Now I come home to the Jeep after being away for 5 days and notice gear oil leaking into the tire from the drum on the passenger side. Would this be the result of overfilling the diff? I would assume the seals are new since I had a regear and axle swap at the same time.
 
That's not a result of overfilling. That's most likely a leaking seal. Even if they put new seals in during the rebuild, they may have nicked one when sliding the axles back in.

The rear axle seals are located at the hub where the axle shaft bearings are, correct?
 
Re-read his question again carefully...

I read that his jeep is leaking near the HUB which is most likely caused by the inner seal failing. The axle seals are located within the pumpkin and need to be pushed out in reinstalled with the carrier out of the pumpkin. He asked if the seal was near the Hub. The seal is not near the hub it's about 3ft away.
Edit: missed it was the rear.. this is info for front.

What am I missing?
I got it. They have inner seals just like the front diff. I thought the rear axle shafts itself had bearings and a seal at the end where the wheels are. By “hub” I meant the part of the axle that sits in the brake drum.
 
So the axle seals are changed in the same fashion as the front axle?
