vauxhall vivaro 1.9di 02 - strange rattle - the sheep@21

when driving especially below 3000 revs when holding a speed a rattle appears like a football claxton type thing as if something is catching something as it spins but accelerate and the noise stops,decrease power and the noise stops until you hold a constant speed again,very annoying, I can't mimic this when not moving and revving engine. Need some suggestions please unless it is obvious,turbo,clutch,gearbox need help please.

i had the same problem after slight clutch judder pulling away, when strip the clutch from fly wheel , they found the clutch bearing had been knoked out of the fly wheel .

we have noticed that the clearance between the shaft and bearing is .42mm i am now trying to make sure this is correct , this is a lot of clearance.

the new bearing came from vauxhall and the shaft is like new , with the orignal grinding marks no ware at all

can anyone advise what the clearance of these 2 components should be ???
