Help with starter grind after start
Help with starter grind after start So I've got a 6.0 out of a van. Starter doesnt grind when it's trying to start but u get a small grind right as it starts up. Is this something I need to fix with shims or something else ? Thanks in advance

Sounds like the starter isn't disengaging fast enough. Shims to move it back a little could help as long as it's still engaging well when you're starting. Too much shimming and you'll shear the ends of the teeth off the starter gear.
Can't shim it to move it back on an GM style. On a ford you could. You can shim the gear mesh to where the teeth aren't as far into the flex plate but that's up and down not front to back.

Thanks for that correction. Last few starters I've dealt with have been on oldies. Haven't messed with one in a couple years thankfully lol
I just dealt with this actually my 00 camaro would grind after it started for a few minutes finally at the gas station it wouldn't start luckily i tapped it with a wrench to get it to start, or i could have rolled it off anyways i got it home pulled starter and the teeth were chewed up pretty bad and had alot of surface rust in it, i changed the starter and no problems since shims and rebuilds on the newer stuff is almost non existent NOT saying its not possible though, im saying a trip to the local junkyard would probably be cheaper and easier, as it seems your starter is not disengaging after startup.
Weird. I'm having the identical issue with a 6.0 and a brand new delco starter. To me, it seems like the starter isn't automatically disengaging once the engine starts. Like the computer isn't detecting rpms to let the starter know the engine is running and to disengage. I could be way off on that.
