Knock rattle and squeak :p drive shaft?

[Parksy87]

Got a quick for you lot, recently done the clutch on smokey (although my mate had started before i got there and the drive shafts were already out) anyway about a week ago iv had an intermittent noise from the front end like a knock and rattle with the occaisional squeak :p it does it in a straight line can hear it more so up to 30mph but not when on full lock soo im ruling out outer cv's i can sit there and rev it without the noise so im ruling out engine/belt, bumps/uneven road doesn't seem to affect it so im rulling out suspension as such, but have jacked it up and have span the drivers side wheel and the seems to be a click from the inner cv, before i go and order a drive shaft anyone have any other suggestions? (or any of my reasons for me ruling things out a load of crap?)

Sorry for the long post
