vibration 93 transport

93 Transport SE. 3.8 vibration in the steering wheel. tires balanced OK.
Axle CV not shuddering when power applied.
Vibration constant grows more intense with speed.
Can harmonic balancer on crank breakdown and cause this problem?

Is this a moderately high toned hum..which would point to wheel bearing (gets worse when turning one direction, gets better the other way).
