What have I done wrong. The splined joint is correctly mated.
Would it be correct to assume the pro-shaft is balanced in isolation from the vehicle? It would seem to be difficult on the car.
Perhaps, despite my confidence, the front and rear flanges have not mated in the original positions. Should this matter?

Crawl under the car with the right size spanner or socket for the bolts that secure the centre bearing to the floorpan. Loosen each by
HALF A TURN ONLY.
Take the car for a drive,
GENTLY accelerating to the speed where the vibration starts then let the car slow naturally to below this speed and return home. Avoid all harsh acceleration and braking while the bolts have been loosened.
Crawl under again and tighten a
SMALL AMOUNT AT A TIME each bolt in turn until they are tight again. Take for another test drive to confirm the vibration has gone.
DO NOT JACK THE CAR to enable you to crawl under to reach the bolts. If necessary use a pair of ramps.
