Ok I have my dryer apart. Now what?

[SIZE=5]ok I have taken my dryer apart to find the grinding noise but I can’t find anything wrong. The belt and the tension pulleys look to be in good working order. The support wheels(?) that the back of the drum is resting on seem like they are in good shape. Nothing is stuck between the drum and blower housing. What else could be making this awful noise?[/SIZE]

Did not see that you had re-posted.
