replacing carrier bearing

[dinnut]

my carrier bearing pretty much fell apart last night/today. the driveshaft is now hitting the crossmember because it came loose. went and found a new one at oreilly for 28 bucks. as far as replacing it... its a 2 pc longbed driveshaft. do i just undo the u joints at the rear by the differential and then separate the 2 pieces of the driveshaft? how is this done? will i have to have the new one pressed on? please help i dont want to put it in the shop if at all possible. thanks!
