This engine does not use any balance shaft.
The upper engine mount is just a torque rod for preventing the engine from twisting too much when torsional force is applied.
The engine mounts below and the transmission mounts are the ones to cause vibrations.
Any vibrations due to bad engine mounts ( unless they are completely destroyed) would not be felt during driving.
If the vibrations are more pronounced during slight acceleration, Roy had it correct. The CV inner joints are bad.
Check the inner CV joints for excessive side play and broken boots. Tell tale signs would be grease splashed all over surrounding areas.
If the vibrations also occurs while coasting in neutral at the speed that vibrations occurs, you need to have the wheels checked. They requires balancing.
