I first checked to make sure the washer was level. The washer is on a concrete floor. After watching lots of you tube videos I ordered all the parts that could be causing this problem. I ordered: Balance Ring, Suspension Pad Kit (3 rectangle plastic wear pads), Tub Suspension Pads(3 curved plastic wear pads), Suspension Spring, and a Spanner Wrench tool. After getting the washer apart it was obvious that the problem was the Tub Suspension Pads they had completely worn away so that only the hold down pins were left. I went ahead and installed all the new parts except for the Balance Ring. Washer now works great. The repair took a little over an hour, but some of the time was cleaning the tub and agitator etc...
