Hi. Welcome to JustAnswer.If the answer I provide for you is helpful, please click 'ACCEPT'. I won't be paid if you don't.
If there is that much play in the front of the unit then the main bearing at the back of the tub is shot.
This is about as major of a repair as you can get with front loading machines. It requires that you remove the drum completly from the unit and then requires special tools to remove and replace the bearings.
I am sorry to be the bearer of bad news but considering that the labor for this job runs well over $500.00 you might want to consider purchaseing a new unit.
Please let me know if you require further assistance, or information. If not please click on "ACCEPT".Thank you.
