Tub Drive Block
Usually when the tub drive block begins to fail, at least from my experience, it would make this noise at the end of the spin cycle when the brake engages. The spin tube and basket drive would stop with the brake, and the tub would continue to spin on the basket drive block. My Kenmore Elite Catalyst has begun to have this issue, and I plan to replace it in the spring when it’s unwinterized. Just my thoughts though.
