loud noise

Help!
My eleven year old, series 90 Kenmore washer is working okay but makes a very loud bang at the beginning of each spin cycle and during the spin cycle makes an unsually loud rythmic noise–sounds similar to an automobile engine spinning over but not firing. Is there a bearing in there that goes bad?

Remove the washer cabinet and check the motor drive coupling (#13 on the diagram). The instructions are attached to the reply.
