I am no expert here but I would think that you are probably fine. Think of how much torque is being applied during acceleration. I would think if the mount was bad then the engine would move more. Maybe someone else can help out a little better here?
I replaced my front mount due to the vibrations felt around the 3,000 RPM mark. After the new mount was in it is nice and smooth. The engine doesn't vibrate as much on startup either. Do you feel vibrations around 3,000 RPM?
