My LG TROMM had never given me problems in 10 years but I knew that noise was not common. I researched it and it showed me this video and that it might be a bad roller. Since I was gonna take it apart I might as well replace the belt and the pulley as well. I had no faith in myself since I had never taken anything apart and put back together, however the video showed step by step so I decided to give it a go. I followed it step by step and it was SUPER EASY. I was very happy with how easy you guys made it for someone like me to follow along and no more noise... Thankyou so much for your help
