If the super charger was re-built it should'nt be the coupler, How is the belt tenioner on it ? My guess maybe thats where the rattle is ?

Mine did the same too, it was the S/C Tensioner, it had worn out really bad, and was rattling to all hell.

Listen down by the tire/in the wheel well, and see if it's down there, if so, its the crank.

Ok ima check on that later on hopefully its the crank pulley..is the crank pulley expensive?? Also is it difficult to change the crank pulley

Its maybe 100 or less if you go used.

You need special pulley puller bolts and a spacer which you can get from ZZP, not sure where else.

It's kind of a pain to remove the pulley. You can get a puller from ZZP for fairly cheap, or rent one from a parts store. As far as a crank pulley price, cheapest would probably be from a parts store.
