Need to drive wagon home, Super bad carrier bushing

Hi guys,
I'm new here, just picking up y wagon tomorrow in fact
Had a question, I need to drive it home but the owner says there's a very bad vibration above 15mph. So i have come up with 2 ideas.
First, use the range lever thingey to put it in 2wd, but I am not sure if this will stop the driveshaft from spinning or not to cause the vibration. Would it?
Second, if that doesn't work, remove the driveshaft altogether. However, I can't find any instructions online or on alldata. I'm okay with mechanical stuff but I figure if I get a response here it'll save me time tomorrow picking it up. Any idea how hard this is? What all it entails?
Thanks guys, I did try searching this forum and google but not too much came up. any help would be really appreciated

The driveshaft is not that difficult to take out. 4 bolts at the front where it attaches to the transmission, 4 bolts at the back where it attaches to the diff, and a couple bolts in the middle that hold the viscous coupling into the chassis. Beware, the bolts on the driveshaft flanges at the front and back are 12 point. Can't remember if they're 10mm or 12mm.
