My S500 coupe is experiencing a chassis vibration between 50 and 60mph. The vibration is more pronounced in the morning when the engine is cold. I originally thought it was coming from an unbalanced wheel. I have had the wheels re-balanced twice at two different places just to make sure and the problem is still there. It almost feel like a harmonic balancer in the engine may be out of balance. Is this possible? I do not know enough about Mercedes engines to know what might be happening. Any help would be appreciated. Thanks.
