Thanks everyone for the replies. I'll try to investigate this further.
Job is for a relative, about 45 min. away.
The last time I was there I checked the suspension rods. They look fine, no broken parts or excessive ware marks.
I had the front off, full load, regular cycle. Flash light aimed at center hub.
I saw no play, wobble, or any out of ordenary movement.
The owner, however, insist it sounds like a train running through her basement.
She even held the phone up, and it did sound louder than when I was there.
The Saga continues.
Q; Is there a way to run the machine in agitation mode with the lid open?
I'm thinking it is a magnetic switch.
