My Frigidaire Gallery washer (top load) is squealing loudly during the final spin cycle. This problem began a month ago, lasted a couple of days, and then the washer seemed to work normally. The squealing would begin about half way through the final spin cycle.

Well, the squealing has started again during final spin. And this time I am also hearing the squeal during other spin cycles.

I have a lot of ideas of what could be happening, but would very much appreciate some help it diagnosing the exact problem and how to fix it.
