Spin cycle loud vibration problems on spin cycle

SOURCE: Washer makes loud thumping after finished spin cycle

Remove washer cabinet (easy to remove)and check that "base pads" (there are 3 pads, located under the main tub)are not worn. In case they are worn (even one of them), you should replce them all. Good luck !!

First plug off the wall. Open the machine from behind to examine if any shock-absorbers(known as dampers) or springs have come off or broken. Your dealer could help with spares. But you could do the job yourself.

Inspect the outer drum to see if one of your springs has popped off. You can also inspect the lower drum area to see if your vibration dampener has worn out or broken free. Also you may need to check your rear bearing just between the large pulley and the drom to make sure is hasn't separated from it's mount.
