H3 Driveshaft on transfer case side

So I started smelling some kind of hot oil after my normal commute to work. About a 15 minute drive. I got under the vehicle and started looking around. When I got to the transfer case I noticed a ton of grease thrown everywhere! I got a close look and saw the rubber boot of the front drive shaft was a bit ripped and didn't seem flush and this is where the grease came from. Do I need to worry about this? It's not making any noises and doesn't seem to effect the vehicle. But I don't know to much about this stuff so any input would be great. I'm pretty good at fixing anything myself so I'm not worried about the trouble of the repair. Here are some pictures to help with some information.

Thanks everyone,
Cory

Your front prop shaft CV boot is ripped, slinging out the grease. It may not make noise now, but eventually it will fail. Probably when it is most inconvenient for you. Having replaced the shaft myself recently I would just get the boot and a new CV and change it out. A reman prop shaft is about 2-3 times that, and you will have a core charge.

Its super esy to swap out the CV on these shafts.

Since you will be getting a new boot with the new CV joint, I just cut the old boot off, unclipped the snap ring, pulled off the old CV, slid the new one on until I heard that click (new snap ring clipping into place). Bolt it up and your done!
