Washer is over 10 years old, but I'm very hands on, and wanted to get some possible advice. I'm leaning towards replacement if turns out to be main bearing. Even if I repaired that, everything else is still over 10 years old. Washes (agitates) fine, goes into spin and initially OK. When it gets up to max RPM, starts banging like an unbalanced load. If I don't stop it, it will start moving across the floor. Goes into the next cycle like nothing happened, gets to spin cycle, and repeats the previous at max RPM. Went through all the previous posts for noisy washer, but couldn't find a post that was close enough to mine to say that the symptoms were the same.
