I have a GE gas dryer that is about 5 years old. I began noticing a rattle when there was a heavy load in the dryer. Got worse as time went by, so I investigated on the web, and made the following repairs in this order: 1) replaced slides and front assembly that the drum sits on (still rattled), 2) replaced the rear hub assembly (still rattled), 3) took off the tension arm, cleaned up, sanded down, re-greased, and put back (still rattled, but much less), 4) bought new tension arm, pulley and belt, greased and installed (rattled more than ever!!) Took apart the dryer again, and the motor seems to run fine without any tension, the fan/blower assembly is secure, and there is no built up lint anywhere. Also checked the mounting assembly to make sure that it was secure and there were no loose parts (there weren't). Put some lighter grade oil on the tension arm/wheel, and this seemed to work for a day or two. Then the rattling came back. Still looking for the source of the rattle which is coming from the front left side of the dryer, it is definitely related to the tension arm, just not sure what piece is rattling. Any help is appreciated.
