I replaced the rear drum bearing kit. I then replaced the 4 bearing slide on the front, which 3 of the four were missing. Since I had it opened and it was over 10 years old, I went ahead and replaced the idler pully and the dryer drum belt. While trying to remove the Idler pulley spring, I broke the tension sensor. I then had to replace that. After doing all that the dryer works like a charm.
