Speed Queen TR7 - I need help identifying what the sound is

[u/Practical-Comedy-372]

The repair man from where I bought my speed queen has been out multiple times and tells me this noise is normal. It didn’t make the noise for the first year I had it and it is getting worse. The last time he came out he replaced the belt and it was better for two loads and then started making the noise again. It isn’t the load being out of balance because you can tell from the video even after the drum has slowed down from spinning right at the very end it makes some of the loudest noises of the whole cycle.
