When I drive over 60 mph and turn slightly to the left or right, my wheels/steering vibrate like crazy. It seems more than a wheel balance issue.

Get it checked at a reliable shop because it sounds like a combination of worn out parts in the front suspension. You need to fix this. This is scary so do it right away.

It sounds like a bad ball joint, possible steering rack issue or possibly shocks. I would suggest stopping by for a free diagnostic.
