Front Drive Shaft CV Joint

It appears the CV joint on the front drive shaft (rear part of shaft, entering transfer case) is going bad. Clicking noise when I turn the front wheels by hand, and a "whirring" sound that varies with vehicle speed when I'm actually driving the truck. I've seen the repair kits (Auto-zone calls it a Driveshaft CV joint and Napa calls it a Propeller shaft repair kit), and was wondering how difficult a job is this? I'm comfortable changing u-joints, wheel hub assembly, etc. Would this be something that's doable? I can't find any directions for it online, not even You-tube. Anyone know?

Thanks.
