my de406 dryer sounds like its binding when you first start it up , i took the blower apart on the blower fan #300-843 you have to brass bearings they fit in bakelite bushing's on the pulley side the bushing is solid , on the fan side the bakelite bushing rotates , is this normal? my dryer drum spins freely, i had the motor looked at and they said it was fine ,any suggestions?
