10 bolt help alright well i decided to try and tackle my 10 bolt rebuild this is the first rear i have ever tried to put together so idk much about it prob my first mistake lol but any how when i was tighting down my pinion i think i over torqued it to were the pinion wouldnt even spin do i need a new crush sleeve its not a solid sleeve its jus a normal sleeve im also having trouble trying to figure out the backlash and gear pattern so before i get any farther i need to know if i need to take it back apart to put a new crush sleeve on it or if it will hurt any thing by over torquing it ?
my suggestion, read this in its entireaty (sp?) before going any further...

ok now the yukon thread says crush sleeve normally takes 300 to 400 ft lbs i didnt even hit 200ftlbs and it was locked and i couldnt turn it so i jus bumped the pinion lightly till it free'd up im assuming i still need a new sleeve but what is with the solid sleeve and shim is it harder to set up like that and if im not taking it to the track does it matter it is an m6 car so im sure it takes some pretty harsh jolts as is so what should i do

Yeah I was wondering about the solid spacer myself. I got one from summit and put it in with all the shims to start with and when I tightened the nut down it tightened down to where the pinion wouldn't spin anymore. I thought that was the beauty of the solid spacer was just get the shims right and tighten it down? If you have all the shims in it shouldn't let it tighten down to where it won't spin right?

ive never used one on a 10 bolt before, but on a 9 inch, you put the solid spacer in and some shims, then torque the bolt down to 125 ftlbs and take your measurement. keep changing shims untill you get 10-15 inlbs i beleive with used bearings and 25-30 with new bearings.

they could be different because the pinion nut is bigger for the 9 inch, as well as a different setup on the bearings.

idk i thought i could tackle this but im starting to thinks its a little beyond me i need to see one get put together and then i could do it but reading the info and not seeing it are whats confusing me
when torquing down the pinion with a crush sleeve, you're suppose to torque it down to the point where it takes something like 20 something to 30 something inch lbs to turn the pinion (by itself not against the ring gear), not just torquing the nut to 300-400 ft lbs. You go too far, you need a new crush sleeve because backing off is not an option. As far as the backlash and shimming, well you just really need to do more research and get the proper tools for measuring and checking the tracking, otherwise the entire rear end will pretty much be borrowing time.
