I ordered two pair to replace both the front and back rollers.  Using a youtube video as a guide, the entire process took a little less than two hours to complete.  By being patient and taking one step at a time, the job can be done by a novice.  This includes time to thoroughly clean inside the dryer cabinet.  The dryer now runs as quietly as it did when it was new.  I estimate that ordering the parts and providing my own labor, I saved at least $200 over calling an appliance repair shop.
