I have replaced the rear bearing, front slide bearings, belt and idler pulley. It ran great for about 3 loads, then began this rumbling thump sound. It isn't consistant, and even quiets considerably when I lean on the door handle while it's running. If I rearrange the load it will also quiet for a few minutes until the load begins a steady rythm of tumbling, then it gets loud again. I can tell the door is a little wiggly but not too bad. There have been a few times when it did not start when pushing the start button, I had to jiggle the door a little and then it would start. When the door is opened while running I can hear a quick skidding kind of sound right before it comes to a stop. I am not sure what other parts I can replace to make this stop. Please help!
