the sound of the car is generally heavy and is mixed with a leaking exaust sound. But I have taken it for checks and its confirmed the exaust is not leaking. I observed the engine mount on top at the passenger side is cracked, could it be the cause?

Symptom indicates possible EGR fault. Is the vibration vehicle speed or engine rpm related?

Both engine speed and rpm, but is worse when the car is in motion. I have replaced the broken engine mount, but vibration is still there.

Check the EGR system.

I have checked all sugestions and vibration remains. I have been told it could be a balance shaft issue, could this be true? That would require a big job if right.

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.

The vibration is engine rpm dependent. Even when the transmission is not engaged, you can feel the vibration as soon as rpm gets to between 1500 - 2500. When it gets up to 3000 vibration stops.

That is more likely to be engine performance related and most common cause is the EGR system.

Is the MIL indicating and have you checked for trouble codes?
