Out of interest how old are the tyres ? ?
If the car has been standing a long time in one position you can get flats forming on the tyres.
This is not visually apparent but can lead to vibration at speed.
A friend of mine some years ago had a Daimler Dart with the same problem. After changing most of the front suspension it turned out that the tyres had flats on them due to long periods of being parked with all the weight of the car on the tyres.
Hope this helps,
