passenger side driveshaft bearing..?

hi all, i have intermittent whirling sound coming from the passenger side front corner. no judder or vibration just a whirring whirling sound that comes and goes..seems to come on when the cars been driven for a bit and rises and falls with the engine speed more than the actual wheel speed...maybe?

anyone had this or know if/which bearing it is likely to be on the wheel, drive shaft or gearbox?

was looking through the 'how to' forums and cant find anything about changing the bearing?

cheers neil : )
