Stepper motor is the most likely suspect. Take it off and clean it. Loads of how to's in the forums.

Yup - sounds like the stepper alright..

Do a search for "stepper motor" - you'll find loads of cases of this.. not difficult to fix...(*)

Unless of course it turns out to not be the stepper.. but I honestly think it is.
