Vibration problem

Hello guys I another E46 more, a 320d E46 136hp (M47) and have a vibration problem when in accelerating. I bought the car with the problem and had both CSB of driveline broke so I bought and put again. The car was best but I yet had the vibration so I was playing with center bearing suplements and playing was a lot of better but I have yet a little of vibration.

In short gears I don't have any vibration and I can accelerate hard without problem but in some larger gear I have some time a little bit vibrations and some times in 3rd gear at 4000 rpm I have a loooot vibration (very hard all car is vibrate).

I was reading a lot and checking. my drive line a first look is good (and another mechanic check) maybe have a little little "gap" but mechanic say that is good. Another thing that i though is a cv joint but I don't found nothing reason in a first look of bad cv joints

What do you thing guys? I tend to think that small "play" of driveline is the problem probably because before owner was running with CSB broke... or maybe is a problem of engine that i found that he has a vibration a little bit of normal

Engine mounts are all news (2 front and 2 rear) and damper engine is new too

Excuse me for my english and thank you in advance
