Samsung Washer WF419AAW - Banging

[Adam Ant]

Hi all. I've got this washer that was out of balance several years ago. Everyone said that the basket must be out-of-round, but I pulled it and found the basket was fine. It was the shaft that was bent by a couple of degrees (prolly from my wife overloading it). I bought a new spider and it worked great for a couple of years.

Then, the same thing happened. Out of balance and banging all of the time. I bought another spider but it didn't fix it. Then, I bought new shocks and that didn't help either.

My question is, should I give up on this thing? What else could be wrong with it?

Thanks
