Samsung Washer WF218ANS-XAC troubleshooting help needed, smoke in the drum compartment
Your front loader drum unit will have a slightly different shaft and bearing system than my top loader drum washer. But I have had the bearings go out twice in 12 years in my unit. When the bearings go bad the high speed spin cycle sounds like a freight train is going through our house. 

I had to purchase a couple of special tools but replacing the bearings was a fairly straightforward task albeit with many steps. So you may want to debug to see if it is the bearings in your washer that have gone bad. 

Note I put your washer model number in to Google and got quite a few hits for manuals and parts lists.
