LOUD SQUEAK

I had the dryer repaired for the same thing by a "professional" 3 years ago. When it started making the same noise again, my son was here and said he thought he could fix it. We ordered the drum support roller kit, which was what was replaced before. After my son took it apart he decided we should also order the roller shaft as it was worn. He also realized the "professional" had installed the wrong drum support roller kit and installed the rollers backwards, which might have something to do with the shaft also wearing. It's working fine now.
