I have a GE dryer about 10 years old. It just recently started to squeak real bad. Its loud and horrible! It squeaks real bad on heavy loads(a load of we towels) and squeaks little to none on light loads(a few pairs of pants). Any ideas what the most likely culprit is? Ive read online that it could be the motor bearing, the glides, the belt, the pulley. I don't want to have to replace all these things, I am looking for the most liekly cause and how to test that.
