Awful rumbling noise when the dryer was running

My Repair & Advice
After I isolated the noise to the drum assembly by removing the drum belt to test it, I replaced the rear drum bearing kit and the idler arm assembly. This corrected the problem for about 30 seconds and then the noise returned. I took this thing apart at least 6 times and in the process also replaced the felts on the drum front and the noise was still there. At one point the only things left were the drum, drum bearing and the front felts holding the drum. Spinning it by hand still produced the rumbling sound. So I took out the drum one more time and closely examined the new drum bearing and noticed that the metal support under the nylon bearing was rubbing against the plate that holds the ball bearing. I bent it down a little bit and the problem went away. I think initially I had a bad drum bearing and when I replaced it the new metal support was not quite the right shape and started rubbing almost instantly, sounding much like the old problem.
