I have a 1979 k10 Chevy pickup. Ive gotten 3 different starters because I thought that the horrible grinding noise was coming from the starter grinding on the flywheel. But the flywheel has absolutely no chips in it at all. It also dont grind when its running. So I had someone turn it over while I was looking at it. And the flywheel turns real slowly and the starter lines up perfectly with the flywheel so it cant be that. What else would it be?

Flywheel may be worn out. Also, did you use the correct shims when installing the replacement starter motors?

I just put that flywheel in about 4 months ago. And yes I used the right shims.

It definitely either a flywheel or alignment issue. The gears can be good but worn. Did you use a new or used flywheel?
