You know if it is broken if you take it out of the vehicle, test it and nothing happens.
you will hear a loud screeching noise from where the starter is trying to engage with the flywheel...if these cogs are worn the starter will slip and make this noise.
This can happen if there is a broken tooth on the starter. It can be a broken tooth on the fly wheel but more than likely it is the starter tooth that is broken. Or the starter sylenoid is bad in the starter.
The cost to fix a broken starter depends on the type of starter and where a person goes to fix it. It can range from $50 to $200 to fix a broken starter.

Starter is not fully engaging or you may have a broken tooth on the flywheel.
if the starter is spinning but not engaging then the bendix (starter teeth) is not moving out to grab the flywheel teeth or the flywheel has some broken teeth. The starter needs to be removed to see what the issue is.
broken tooth on the fly wheel if your starter is turning over and not just spining what's wrong if the starter's just spinning?
Broken starter drive? Broken tooth on converter/flywheel?
