I googled the problem I was having with the dryer. Then I watched a youtube video on how to take the dryer apart. The drum rollers looked bad and I also noticed that the dryer belt had a bad spot on it. AppliancePartsPros recommended to change the rollers, belt and idle pulley. So, I bought all three parts and it was cheaper than a service call from a repair man. I replaced the old with the new and no more noise while drying laundry.
