In the last month or so when starting, sometimes I'll get a GRIND and no start.(maybe 1 in 20) Usually will fire up next try with a little nudge to the truck. Pulled the starter, teeth look fine to me and should be getting full power.
Trying to look at the flywheel but it's a little hard to see...But also doesn't look significantly worn down or messed up. The inner wheel does show some sign of wear, and there was some buildup of metal shards in the housing.
