Two things Iíd check as this drive train is pretty simple with few variables which is good. Take your agitator off and make sure your spanner nut is good and tight holding your basket to the drive block and also the drive block is locked securely to the drive shafts tabs and hasnít jump off and bent or broke them. If all is good there sometimes the balance ring cracks and drains out too. The latter is rare but Iíve seen lots of oddities including that for no reason. Good luck.
