Dryer was making a loud squeaking noise

We disassembled the dryer, which was really easy because we viewed a video on YouTube, to determine the problem. One of the support rollers had all but disintegrated. It appeared as if the belt was in good condition, but we decided to order a new one as well as the drum support rollers. We found PartSelect online, and using the model number of the dryer, we were able to determine the precise parts we needed to do the repair. We also ordered some related parts in case we found the problem to be more extensive than originally thought. The parts came within two days. We were able to view videos on the PartsSelect website for step by step instructions. The dryer was surprisingly easy to repair, and with the new parts runs like new! As a note - we didn't open any packaging until we were ready to use the part. We were able to return the unused parts for full credit. I couldn't even get a repairman to come through my door for what it cost to repair our dryer.
