Hi guys, bit of a wierd one, my car clunks when its warm and in gear under acceleration and de acceleration but not much when it coasts..first of all i thought something was loose so i had a look, then i took it on ramps to look underneath and everythings tight including the drive shaft, strut all looks ok. THe noise comes from the front right, i cant think of anything else apart fron driveshaft or even gearbox?!? the car drives fine like normal and the noise comes in like a complete revolution, again backwards or forwards

can any one shed any light
