Hi,
According to this website the washer was most likely manufactured in 2011.
If the drum is not sitting straight and it wobbles when in use it may be a problem with the suspension rods part # W10780048 that hold the tub in place. (example only to show what part looks like and possible cost - there are other suppliers.
Here's a link to a parts supplier that may help.
If you find the problem with the washer and it is something else, use the supplier linked to find the part number for the part. Then search online using the part number only to find suppliers that suit you best.
