    hi, I have a 87 yj that goes through starters and flywheels like there's no tomorrow! The mechanic I have now is pretty good and fixing a lot of other problems ( which I'll get into later, after I fix this headache) but he can't find the right starter for. It. He says the ones he keeps getting from parts houses are not the right ones. Something to do with the distance the bendix travels into the flywheel? It either goes too far or not far enough? Does any of this crap make any sense? Please help!

    Thank you. It it has the straight 6 cylinder I'm sort of having a brain fart. I believe it's the 4.2?

    Are the starters you are installing OEM?

    You could also have a bent flywheel. Take it down, lie it flat on a "flat" table and observe for war-page.
    Are all your bell housing bolts run up? Look in there to see if you have any gaps between the bell housing and the motor end.
    Yes also check to ensure you have an OEM starter. Don't be tight and buy a $25 to 35 lesser starter...that is exactly what you'll get.

    Ok, I am going to toss an opinion out...take it for what it may be worth or not worth.

    A parts house often make mistakes. However, they do not generally make them over and over let alone keep making the same two mistakes (too long/short) over and over. And when you start having the exact same issue with two different parts houses...well, I think the problem lies somewhere other than the parts houses.

    I have seen flywheels not installed correctly (backwards) or bent as Matt says above. Hell, I even saw a crankshaft issue once.
    I have seen the wrong flywheel used a few times over the years.

    Remember, it only takes one bad tooth on the flywheel to start eating things.

    To add to what others have said I recommend OEM starters. Also did your mechanic change bother the starter and flywheel together? If one has a bad tooth and you mate a new part to it it will ruin the new part quickly. Bite the bullet and install factory parts would be my suggestion
