Product review (5 stars): New Idler Pulley Makes Dryer Sound Like New Again
Purchasing and installing this item cured a squeeky, noisy clothes dryer.  We've had the dryer for over 25 years now and have kept it operating by changing out a number of worn parts:  the heating element, the door microswitch, the front door glides (twice), the rear bearing and seat, and the belt (several times).  Sure beats dropping $500 on a new dryer and they are so easy to fix.  Even replaced the motor itself when the starter circuit failed.

But the noise was really getting unbearable, and changing out this simple, inexpensive part made that all go away.  Very pleased with the purchase and the results.
