Samsung washer 6 years old vibrates like it getting ready to take off. Have it torn down and inspected everything I have read; bearings are good , spider gear looks good ( except for typical corrosion that builds up due to bad design) but not broken, machine was level good on a pedestal. Shocks have been replaced. I'm stumped at this point, does anybody have any information that I could be missing. Thanks in advance. Bentley
