Has anyone felt a slight vibration in the steering wheel at normal highway speeds (not a Wheel balance problem)? After going through 4 wheel balalnces to correct what I thought was an out of balance wheel, the Service Manager told me there is a harmonic resonance that the drive train produces in V6 hondas that pulse through the body during acceleration and deceleration as highway speeds and can be felt inthe steering wheel. It's slight but perceptable. I ran the car through its paces up to 110mph and it's rock solid for the most part except the slight vibration I'm describing here - has anyone else felt this?
