Help with engine noise ( Vid) Merc. 3.0 lx

[fishinrado]

Ok, here is a Vid of the engine running without the lower drive and it sounds Normal! So I'm guessing the Gimble bearing or the u-joints don't have to be that bad to vibrate? Hoping someone can chime in about any of the above post on u-joint recognition and anyway to test. As I mention visually everything looks fine but with confirmation of the engine not the culprit I'm not sure what else it could be .
Thanks!
