dryer wouldn't tumble with normally large load - very noisy when it did tumble

I disassembled the dryer using instructions from the following website for White Westinghouse (pictures really helped)
After removing the drum, I first noticed that the grouding ball was sitting on the bottom of the dryer (along with much lint). I then saw that the bracket for bearing support cup and the bearing support cup were both worn well past use. The bracket had been worn down about 1/4" to the SE with matching wear on the bearing support cup. There was a hole in the bottom of the bearing support cup (hence the grouding ball on the floor of dryer).
I installed the new idler pulley assembly and completely vacuumed out the dryer (I didn't know lint could get so stiff!). I installed the new parts from the kit once received (and the new belt bought previously) and the dryer works great. I'm so used to the obnoxious squealing that it seems odd to be so quiet.

The internet is a magnificent thing!
