My started all the sudden started spinning freely. It no longer cranks the motor over. It was working fine about halfway through the day yesterday.

Then when i tried to start it again it just spun freely and doesn't actually turn over the motor. It jst sounds like it's spinning fast in there?

do i need to get a new starter or what most likely happened here? I've had some people telling me that depending onw hat is broke i may have to split the case. I really dont' want to do that haha.
