Noise while accelerating

[Tim Nicholson]

anyone have an idea what would cause an increase in noise and viberation during acceleration / I can feel it in the seat, steering wheel, its fine once a crusing speed is reached or during coasting. It almost feels like part of the exaust system is making contact with the body.
Thanks in advance

I had vibration only when accelerating between 40 - 50mph. I just about swapped everything. The root cause of the problem turned out to be the half-shafts. I did not get any vibration while cruising or coasting.
