Product review (5 stars): Electric dryer drum roller works good.
Heat from the dryers heater causes the drum roller on the one side of the dryer to experience a drying out of the lubricant that is impregnated into the bushing in the roller. My Maytag dryer is over 30 years old and has had a loud squeal from the bushing in this one roller for more than two years. I tried lubricating it with silicone lubricant, but found it to be a temporary repair. Now that I have had the new drum roller installed for a number of months, I have no more problem. The dryer runs quietly. I would recommend this repair to anyone.
