AWD carrier bearing?

Got an AWD vue with worn carrier bearing. Does driveshaft turn during typical, dry pavement use? Seller said it vibrated when driven. Always? Or when AWD kicks in? I removed shaft today. Yes, it has a very sloppy rubber bushed bearing. I might replace bearing and install driveshaft, or maybe not.

Why not just fix it right, and get it over with?

well, seller said it vibrated in some situations so that means the driveshaft does turn, sometimes.
i suppose it would be nice to have a working awd system
