My front loading washing machine is acting out of balance. It's not too bad when spinning empty but if there are clothes in it, it rocks and makes loud squeaking noises. I've leveled it, front to back and side to side are within level using a 4' bubble level. When it's spinning I can see that the drum moves front to back relative to the door.
Can I open it and re-level the drum? Any idea how to level the drum?
