My guess is that the wobble is faster at higher speeds and has turned into a vibration.
is the wobble limited to the steering wheel and as speed increases the car shakes, then it levels back to a shake in the wheel?

aside from speed, does acceleration / deceleration affect it? have you checked the inner tie rods for play?
