Tom, there may be one other thing you want to check on your hubs. I had one
set balanced years ago and it definitely helped, however with the car on
jack stands I still noticed the hubs still ran out. I measured the distance
from each lug hole to the edge of the rim and realized that the hub was
machined off center.
The fix was to give an old hub for the machinist to hold in the lathe. He
then took turned both the inside and outside so that the drum would be
concentric with the hub. After this I didn't expect them to take much
weight to balance, but they did. We tapped pieces of scrap steel and
screwed them on.
My car still had a little shake, until all earlier threads convinced me to
put on new tires. My car is shake free now.
Hope this is clear.
