Replaced the front support bearing and bearing slides a month ago and now I'm getting a rhythmic rattling when the dryer has a wet/heavy load. When the clothes begin to dry out or the load is very light there is no rattling. I've taken everything apart again and put it back together but the problem persists. It seems like it may be coming from the bottom left, where the idler pulley is located. The pulley seems to have quite a bit of play on the idler arm.

I don't know if it will work, but I've uploaded audio of the rattling here.
