have your front tires rebalanced.
tension on the motor causes a slight vibration in the on the frame of the vehicle
Check the wheel balance
Usually that's caused by out of balance wheels. Take the vehicle to your tire store and have the wheels balanced.If that's not it, take it to a good suspension shop (not a tire store, I don't care what they say) and have it checked by someone who only does suspension and steering.
My guess would be wheel balance.
It's almost always a wheel balance problem. Take the vehicle to your tire store and have the wheels rotated and balanced using a SPIN balancer. The cheap "bubble" balancer does almost no good.
Is based on vehicle weight and road conditions. you also have to figure in the reaction time of the driver, condition of the brakes, tires, and vehicle overall. however you can figure that at 60 mph a vehicle will travel one mile per minute

If it happens when you are driving fast (60-70 MPH) it could be that your wheels are out of alignment.
