    Agreed. I will double check everything again. Pretty sure it's down all the way, when I change shims I can see some rub marks on them. I was thinking exactly what you said about not a lot of change. From other posts I've read and articles, most 10 Bolt 8.5 rebuilds guys are usually around .030-.035, .032 .033 average. Stock shim was .040 and that's what I started with. I thought I would have found the right spot by now. I will check it all again later after work. Thx again for all your input.

    That's great. Yeah, try .021 or .022 and see how that looks.

    This is why I'm not crazy about trying it for my first time. Gonna have to, though. I wanna be a big gear head, too!

    To deep again. See the dark line at the root of the drive pattern?

    Almost there. You're closing in on the sweet spot! Then the fun can start with crushing the sleeve....

    Not trying to get ahead of myself, but in addition to the crush sleeve, I also got the ratech smart sleeve, and also a solid pinion spacer and shim setup. Any opinions on what I should go with when the time comes?

    If you already have both, go for solid. More work to set up, but once you're done you can just reuse it without pulling the pinion. You'll be thanking yourself if your seal starts to leak in the future. It also adds to the strength of you rear end a bit, by supporting the pinion bearings without the possibility to compress like a crush sleeve can (not everybody supports this theory although).
