A driveshaft will vibrate at a much higher frequency (as it runs about four
times as fast) compared to a wheel related vibration. The 50-60mph
vibrations are normally something running at wheel speed.
I am not that familiar with TR's - how do the wheels locate on the hubs? Are
they centred by the hole in the middle of the wheel onto a spigot on the
hub, or (like AH Sprites) just by the wheel nuts? If they are the latter it
is possible that a in spite of being checked and balanced, they do not run
true to the same axis when on the car.
