I'm pretty handy and have already done service on my dryer a while back - it was making thumping noises so I took it apart and cleaned out lots of dust and checked the belt, pully & rollers. It has been fine for 5 months. However, it started making an even worse noise this week and I need some advice on whether the visual I see is a more serious problem than just the repair kit (pulley, belt, rollers). There is black oily dust all around the bottom of the unit and on the motor. Could not find a post anywhere that describes what I see. Dryer does dry but makes a god awful noise.

I tried adding a picture but kept getting an error. Here is my dropbox link with pictures and a video. Any help would be appreciated.
