my 69 chevelle starter has a grinding sound

is the starter on when the car is on?

if it happenss once in a while, you might have a tooth missing on your flywheel, otherwise the bendex might not be kicking out all of the way. It is only 5 bolts to pull the starter out and get it checked.

its starts but very heavy grinding sound when cranking up. but not after its on

it sounds like its partally ingaged. it might be bad. i hate to say it but also check your flexplate. you may have to change them both.

check everything stupid

jk

My 1969 chevelle need to find clearance between flywheel teeth and starter bushing.
