Belt Noise
 

Need help! I started hearing a cherp from my belt area, I sprayed some wd40 on the idealer pulley and it went away. I replaced the pulley noise still there. Looks like what happened is wd got on the belt itsef and thats what made noise stop. I replaced the tensioner and belt no help. When I spray belt spray on the inside of the belt noise gets worse, any idea's?
