This allows the engine to move/rock through a small amount without transmitting vibrations to the bodywork - typical of idling/low rev conditions. Important in these cases to use the correct bush/mount, which may have strategically placed air-voids or thin rubber.
Exactly so.
This is why any alignment marks have to be strictly observed, when replacing bushings that can fit in more than one orientation.
