I have a Frigidaire Gallery Series dryer. About 6 months ago the heating element went out. At that time I replaced the heating element, the drive belt, and the rear bearing. Now I have another problem. After about 5 minutes it starts to make a noise. Sounds like something rubbing. With the dryer off and tumbling by hand I can hear some clicking. I took the front cover off and ran the dryer. Once the noise started I started carefully prodding around. I noticed if I push the belt tensioner pulley over the noise changed but didn't go away. Any ideas??

Thanks
Dan
