Haven't seen this talked about.

Yup. Pull the starter and check the teeth.
Think it is bad now wait till the teeth actually go and keep your fingers crossed the teeth on the starter side go.
Mine went on my Explorer and man that was a heck of a racket. Thankfully it was in my driveway.

Try this one - sound is near the end.


If that is the sound, the starter should be removed so the flex plate teeth and starter drive teeth can be inspected for damage.

WINNER, WINNER. Chicken Dinner! Thank you. THAT is the exact sound. Thank you, thank you.

There are few things that can cause that sound when starting an engine. The most common is broken teeth on the starter drive gear(pinion) or the ring gear on the flex plate.

This is broken teeth on a flexplate:
