Our washing machine recently began to shake more than normal during spin cycle & I have replaced the shock absorbers which improved things, but at low spin speeds it still shakes more than previously. Should I have replaced the top springs at the same time as the dampers or could this be an early indication of bearing failure? There is about 2mm end float but no slop when moving the inner drum, or could it be something different all together. The weights seem to be ok, ie. not loose or cracked. Thanks
