    It can happen if the bearing wears out. It has to be occasionally cleaned, regreased, and sometimes needs new rubber seals, or just replacement. Friction-related heat can definitely warp an axel housing. If it’s bad enough the wheel will seize. I wouldn’t be too surprised if there was also lateral wobble in the wheel.

    A cross-threaded cassette might also produce this effect.
