So, hanging the whole powertrain from the three  mounts by jacking up the 
body is good?
Look at the design of the forward  mounts. I don't see how you can compromise 
these mounts by jacking up the  differential.

The  powertrain is always hanging from the mounts.  There are minimal thrust  
and braking loads because these are handled by the suspension pieces.   I'm 
not saying the engine mounts aren't robust--just that they weren't  designed to 
take a reverse shear load greater necessary for the  powertrain alone.  I'm 
not saying you've damaged any mounts your way as  your earlier posts (which I 
did not criticize) said you only raised the car  enough to get the jack under a 
jacking point.
