Wasing Machin

I have Kenmore washing machin, Its work but when it gise fast spining that time it make to much noice and I feel that in side is hittin with some thing ,is not running in center but on right and left side moving and hitting some thing, what should be problem?

Our side by side doors won’t stay closed…which leads to constant running and ice build up. Had a repair guy out and said the gasget is discontinued. Ordered the door closer parts for both doors, but any way to find a freezer, frig door gaskets for this model? We cannot afford a new appliance right now and the refrigerator freezer works well when the doors stay shut…any suggestions?
