You might as well take it apart and inspect it. Your warranty is shot anyways. My bearings were too loud and due too the big hassle with trying to get quick warranty issues solved I decided to replace the bearings myself. There is a posting on RC that walks you through the process. Bearings are alot cheaper than a new motor if that's the problem.
