Just to keep this thread alive as the LG nightmare does not seem to be going away. I had the same experience with my LG WM3570HWA. There was enough information on this thread to give me the courage to take a look under the hood. What I found was just like everyone else, my bottom counter weight on the washer floor. I did not replace with washers but just made the bolts very tight and added loctite. I have had this washer for 3 years brand new and it has always made some type of noise during the spin cycle. Recently the sound has become much worse, our machine is on our second floor and I swore it was coming through the ceiling. It also grew legs and walked around our laundry room. Long story long, this reattachment of the weight fixed everything (makes me think the weight was never properly on the machine from the store), prevented a service call or new purchase and the machine has never ran so quietly! Thanks to everyone that posted this similar problem and the the solution!
