I have a whirlpool top load washer, model # LSR6332KQO, that will no longer spin smoothly. It wobbles even when empty. The tub is loose from side-to-side, but not up and down. The agitator also seems slightly loose side-to-side and up and down. Any idea what may be the problem. I do not see any visble belt. There is no access panel on the back, so I have tipped it at an angle, front side down. Is this problem easy to fix or better to look into a new one?
