Axles and output shafts just don't break...I'd put my money on the CSB. I have E12 sockets, impact and a universal joint. Drop the exhaust, some covers, and the heat shield. Then you can inspect the center bearing.
I'd also replace the flex disc, the lock nuts for the flex disk, buy a cover for the CV joint, and repack with grease if you end up replacing the CSB.
I think you're right, its the CSB. At first it seemed to be an axel issue but the noise has tapered off a bit but its still there.
Does anyone have access to a lift? I don't think this job would be too fun with the car on jackstands..?
