Ok at average speed of 55mph going in a straight line (no vibration)

If I merge into the passing lane (no vibration)

If I merge into the regular lane from the passing lane OR go into a slight sweeping right hand curve. (bumping in the steering wheel occurs)

I feels like it bumps, as fast as the wheel is turning. the slower I go the less it occurs.

Normal driving around town and under 55mph I dont feel it.
