Product review (4 stars): Before my dryer sounded like a catfight on helium
If you are mechanically inclined or have a can do attitude, you can save yourself a bunch of money and do the work yourself. Before my dryer sounded like a catfight on helium, now its as smooth as day one.

That part that was bad on mine was the white roller, but you might as well replace all of them if you take it apart.
