After reviewing a video on repair of this type of machine it was noted that a spring was missing between the tub carrier base and the tub. It is a spring about 6 inches long and about .75 inches in diameter with a hook on each end. I found one in my junk box and installed in the appropriate holes. This made a little improvement but not much to the knock/wobble of the tub basket in the spin portion of a cycle. Next I put some thick foam board inside the outer shell hoping it would stop the noise/wobble of the tub . I only put it on one side at least so far but it did not stop the problem. Unless I can come up with some other remedy I will scrap it. If anyone has some other suggestions I am eagerly hoping to hear from someone.
