I'm not sure what the question is, but I'll do my best to elaborate on the Center Support Bearing. Basically, it is a free-spinning bearing that keeps the driveshaft aligned properly. Without this bearing, the driveshaft will "wiggle" and knock around, possibly causing damage to the driveshaft's U-Joint. I've been told they are around $250 from Nissan.
It's actually in the center.
its the center carrier bearing in the 2 peice driveshaft...have it replaced or go to a 1 peice driveshaft
