[Updated] Checking my tire pressure today and found a possible break leak?

Can confirm diff oil. I did the sniff test and finger test on both. I cleaned the area off and am going to see if it comes back in the morning.

Here's a picture of the drum. The darker area is where it was leaking.

 

Well I didn't have to wait until morning. I drove 5 mins to class and some drops are back on the wheel

 

Better add diff oil until you fix it. Would hate to see you smoke your gears!

 

I'll get some haha. I'll try to get under there tomorrow if the snow holds off. I'm also going to check the diff breather to see if it is working.

 

Finally was able to pull the breather and it was stuck full of sand and dirt. I have the parts ordered to relocate it so that won't happen again
