Well he's saying that the thumping is coming from the car at idle. The carrier bearing isn't rotating during idle.
The main cause for the driveshaft to be thumping against something is due to a bad tranny mount allowing the tranny to sag, thus allowing the front drive shaft to sag. Even if the carrier bearing is bad, the carrier mounting brackets will not allow that part to sag while stationary. Unless the two bolts holding those brackets are loose. The rear drive shaft piece would sag due to bad subframe bushings.
And if you've replaced those with upgraded bushings, you've raised the drivetrain UP. bringing it closer to the frame. Can create all kinds of rattles.
Good luck.
