Brethren:
First, a needed correction. Note the spelling in the subject line. It's
spelled with an "iu", not a "ui" and pronounced "gee-u-bo".

Right. On the Porsche 944, the transaxle is attached to the underside of
the body pan with rubber mounts just like engine mounts. Because the engine
and transaxle are rigidly attached to each other, BOTH of them have to be
able to float just a little bit. On our Alfettas, the transaxle could have
been mounted DIRECTLY to the body pan, without any rubber mounts whatsoever.
The giubos take care of the alignment issues. But I suspect Alfa included
the rubber transaxle mounts to reduce the transmission (Have I discovered a
pun?) of vibration and gear noise to the rest of the car.
