Leaky Transfer Case

I took my 2003 Rubicon to Jiffy Lube for an oil change yesterday and the mechanic said my transfer case was really low on fluid. I looked underneath and saw some dripping from the rear output shaft. (See the picture.) I'm guessing it's a pretty bad leak because it's spraying transmission fluid all over everything when it spins and the underside of my tub is covered in fluid. Am I correct in assuming that the rear output shaft seal needs to be replaced? If so, is this a difficult repair? How do I do it?

Just found this searching for a similar problem. Mine just started leaking this week. Today I saw fluid on the garage floor slowly dripping from my trans case skid plate, which is wet all over with fluid. Doesn't look like a fast leak, but relatively significant.

I just had my speed sensor replaced becuz for some reason it was just hanging there and fluids were coming out from the transfer case. Good thing it wasn't crack or anything since I lost a lot of fluid from driving nearly 3 hours and not noticing it leaking!!!

FYI... I figured it out. It was the seal from the rear output shaft. Apparently, it's fairly common with Rubicons. I replaced the seal, refilled the t-case, and it's all good!
