Model # DEGX1, the dryer was operating fine, but would make a squealing noise during operation that was more noticeable with heavier loads. The source of the noise was the drum bushing that is located on the right side of the unit. These bushing will dry out or fatigue and crack with age resulting in an objectionable noise that increases with the size of the load. Replaced the bushing with a new kit (part # 479332 if you can find it) and it now sounds great.
