Without seeing your car it's hard to tell what the problem is. The starter turns the flywheel which turns the crankshaft and your car starts. If you dont have any problems starting the car, chances are the flywheel is ok. You may want to check the belt, pullys or anything else that is bolted, like covers,etc.etc. Goodluck
