You sure it didn't just get slung into the muffler by the drive shaft??? When the output shaft leaks it will travel onto the yoke and splatter onto the muffler. Take a good look.

If you are saying that the transfer case itself got hot then I would be inspecting the amount of fluid still in the transfer case. Hopefully no damage was done if it was real low. The good news is that the seal is relatively easy to replace. Undo the bolts on the rear universal. Put electrical tape to hold the end caps of the universal joint in place while it is out of the yolk. Pull the drive axle to the rear and it will slide out of the transfer case. Use a seal puller to pull the seal out. I used a piece of abs plastic pipe to tap the new seal into place. Put the drive shaft back up. Done.

Time to inspect the output shaft splines carefully. Maybe a transfer case from a junker is in the offing. Getting a new output shaft may be pricy. Is your jeep lifted? May be the cause of the broken slip joint. May have stressed it near the end of its travel on or near full extension of the wheels while under power.

The crack looks to be towards the end of the slip joint. The wear on the surface of the slip joint appears to be towards the end. The surface worn silver is an indicator of where the seal has ridden. The rusted part appears to have been maintained outside of the area where the seal is. This looks like the slip joint spent most of the time working at its end of travel and not fully engaged.
