How to replace a dryer drum support roller

This DIY dryer repair guide explains how to install a drum support roller. The drum support roller holds the dryer drum in place as it turns. A damaged or worn support roller bearing typically makes a scraping or squealing noise, and the drum may make quick thumping sounds if the support roller has a flat spot. Replace a worn or damaged drum support roller using the manufacturer-approved dryer part.

The video below shows a gas dryer, but the basic repair is the same. This repair procedure works for Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate dryers with a lint screen housing located in the top dryer panel.
