The drum is bolted to a three fingered thing called a spider.
The spider has a spindle which goes into the main bearing.
If one of the spider arms breaks, the drum flaps around and bangs about while spinning, and makes a horrendous noise (but doesn't screech or squeal).
It's easy and relatively cheap to fix for someone who's mechanically competent - but it's fiddly and quite a lot of effort, so probably expensive to pay someone else to do. I'm not an expert, but have had this fault myself and fixed it myself.
Really, you need Chuckfickens to answer this - I believe he used to
service washing machines.
