Sounds like you have already got some good advice. If the starter has been grinding very much, you may want to have something written down about possible flywheel damage, for future insurance for when your warranty runs out. Flywheel replacement is not a small job, and I've seen alot of ground down flywheel teeth. This may be or may not be a problem, but just something to consider. Good Luck !
