Starter or flywheel no start grinding My car has been a nightmare problem after problem and would love some help. So recently my starter started grinding right after starting. I drove it for about 10 days before I decided I didn't want to damage anything, so I went to buy a starter and following the advice on here I bought the truck starter (5.3) (Remy 96232). Upon removal of the old starter I noticed a few flywheel teeth that were half chipped. So anyways I put the new starter in and started her up, while cranking I heard a weird type of scraping noise I didn't know if its just the way this new starter sounded or if it was grinding again. After the third day my car would no longer start and the starter would only spin. If i push the car while its in gear than the starter would start I did this about 3 times and each time it gets worse and worse. I have a billet steel flywheel (18 lb)and I am assuming my flywheel is done for. What I dont understand is how come this new starter was constantly eating up the flywheel teeth. Did I need to shim it??? I noticed some metal threads on the floor when I swapped starters I'M assuming its from to much tq on the old starter bolts but still the new starter was against the block nice and snug.

Remove the starter.
Make sure you have the right one. Google images or check p/n's.
Check the starter bolts threads to see if they have ripped threads out of the block (it seems they have. This could be your problem. You might need to repair the blocks threads with HeliCoil).
Make sure you have the correct bolts and not some undersized shitty random ones you found in your garage.
Check the engine block - around where your starter bolts to for damage or welds (previous damage).
Screw the bolts back in the block and wiggle the bolts around to see if there's play.
Install the starter, check if it's mounted straight and check for play (try to move the starter left/right - aim for your b/r and b/l wheels)
Check the starter and ring gear gap. There are heaps of posts/threads regarding this (using a pin between the teeth to measure with). Do a quick google search.
I'm pretty sure the flywheel stops in random spots.

Ok I checked the area surrounding the starter and the starter mount bolt holes, the starter is nice and snug in there, when I installed my old starter back in I can get it to crank a few times without grinding, so I'm pretty that truck starter wrecked my flywheel up. It's so weird, maybe its because my flywheel is aftermarket, I don't know but the truck starter with 9 teeth just grinds day and night. My flywheel teeth look wrecked. I have taken some pictures of my flywheel. And yeah I think I need a new one and also going to grab a proper 11 teeth starter that looks like my oem unit so the new one doesn't get chewed up again.
