diesel 2.4 K reg

[waz&cj]

Hi, my truck as recently started giving me trouble, when I am accelerating up to 25 miles an hour, my truck starts to vibrate, if I take my foot off the accelerator, then the vibrating stops and coasts smoothly, vibration gets worse the faster I travel, has anyone got any ideas?
