Which is it? tub or agitator loose? If tub probably the drive block broke out it's center. It's really called the spin basket, and a ring nut holds it to the basket drive block, and so when the shaft spins so does the spin basket, till the basket drive block breaks, to check it out, remove agitator, take a blunt punch, & hammer and knock the ring nut loose and remove spin basket, look for broken out the center fo the cast aluminum drive block, piece o' cake |
