Ordered four (4) rollers through Appliance Parts Pro....followed video instructions from Appliance Parts Pros on proper installation. Install time was three hours, changed only front rollers, but took drum out to make sure back rollers were in good shape, they were in good shape so left them in. Cleaned inside of Dryer compartment thoroughly along with outside. Inspected Drum and Drum belt....Belt had small cut and is starting to fray. Will have to replace soon. My advice is to purchase belt along with rollers, replace rollers and inspect belt, replace if needed.
Overall the video was very well done....
