HELP >> Loud clicking sound during agitation cycle

Hi All,

There is a loud clicking sound coming from the washer during the agitation cycle. It either goes away or is much less noticeable during the spin cycle. I have attached:

1- A sound clip where you can hear the clicking sound especially close to the end of the clip (i.e., in quick succession).

2- A couple of picture of the back when I opened it up. The spider pulley and belt seem to be in pretty good condition. Probably replaced at least once since the appliance was bought.

3- I did notice a hole in the drum …not sure if some screw went through it in to the body of the drum or something else.

I don’t know what this loud clicking sound could be. It doesn’t sound metallic …it sounds like a hard plastic sound. When you move the drum by hand, the sound is not there. Could it be a relay or something like that?

Please help
