starter or flywheel problem??

02 6.6 deisel, for last several months from time to time my starter grinds on the flywheel. I know I need to deal with this, but need to find the time.

Anyway short of pulling tranny how will I know if it just the starter of the flywheel grinding away.

And how hard is it to replace a starter on an 02 6.6

As far as I know, just pull the starter and have it tested. Make sure they run repeat tests back to back on it. More or less a heat soak test. Sometimes they will test fine and then when they heat up they will act up. and look for messed up teeth on the starter gear. The starter might not be engaging all the way and causing the sound. If it's not that then look deeper at the flywheel. Hope this helps. Had this problem with another truck I had long ago.
