a thunderous noise when dryer started & ran

the blower wheel was not turning with the shaft. so i figured the spline or D shaped bore was stripped. so i connect with partselect & read about it.i ordered the part from partselect and installation was not that hard at all.i wrecked the snap ring so go get the tool & make it easy on yourself. had the dryer purring in about one hour. thanks to partselect. jerry
