vibration/shudder at 70 - possible alternatives (other than wheel balance?)



I've heard of those! Some guy was up in our neck of the woods selling 
vacations hunting them. Huge antlers on them things right?

I turned him down, but took the guy up on the sale of the bridge in lower 
NY! I am still waiting for my first check from all them toles collected!
