Drum Support Rollers
The drum rollers are located on the back wall of the dryer. The drum rides on top of the rollers and they support the drum in place. With time and the amount of use of the dryer the metal bearing inside of the rollers wear out and the dryer starts to run loud.
Front Drum Teflon Slides
These slides are made of hard Teflon strips and the front of the tumbler drum slides on them instead of using wheels. With time and usage they wear out and the drum starts to rub metal to metal making scraping sounds. They are attached to the front support panel with aluminum rivets. Watch the video to see how this repair is done.
This wheel is like a fan and it is sued to suck air from the outside, pass it through the heating element and through the tumbler then exhausting to the outside. The hole in the center of the wheel is in a D shape and when the hole gets rounded the blower wheel gets loud and doesn't move the air properly throw the dryer.
This part uses a wheel that the belt rides on top of it. It is used to give the belt the proper tension. This wheel is made of hard plastic and eventually will wear out and becomes noisy requiring to be replace. Watch the video according to which one your dryer uses.
These parts are used to move the clothes inside of the tumbler so they don't bunch up and dry faster. With time the screws that hold the drum baffles in place become loose and the baffles start to clank against the tumbler when the tumbler turn around. Tightening the holding screws takes care of this problem. Watch the video that show how this repair is done.
As the motor gets older the bearings wear out and the motor makes noises. There is nothing you could do to the motor except replacing it with a new one.
