driveshaft center support bearing

[SWEET7T]

I found my vibration... My center support bearing is completely shot. The rubber is all chewed up, so my driveshaft can move around in there.
My question is, what all do I need to replace it? The truck is my daily driver, so I'm hoping I can do this in a couple hours on a weekend. I already know I will need to pull the driveshaft out, but do i need to seperate front & rear piece of the shaft? Does the bearing assembly just slide down the shaft? I've never owned a truck with a support bearing before so all info is apreciated. Thanks.
