CV axle vibration?

On a 2005 Scion xB I have a moderate front end vibration above 50mph+ only. Assuming everything else is within spec, how likely is it that this vibration could be caused by one of the CV axles? The most runout I found was .030 on the passenger side axle. Any thoughts?

Tire balance?

I’d look at tires and wheels before the CV joints/axles.

How many miles on this vehicle?

Switch wheels/tires from front to rear and see if it makes any difference.
