It appears the heavy vibration( imbalance) is when the engine is under load. This morning I was in 3 gear and started feeling it at about 55, I down shifted to 2nd and imbalance speed up. This confirms it is not in the tires. Any help is appreciated, even WAG's
Thanks Mike

This is the thought process used to fix any vibration.
It's all about separating the potential root causes (so that you
know what you
don't have to worry about - so you can focus on what you
do have to worry about).
