putting gears in a 8.8

im trying to put 4:56 gears in my 8.8 and my pinion will not tighten up at all i think i just havent crushed the crush sleeve enough yet but do any of you know where a good writeup is on this? ive searched and just find the same thing and it hasnt helped, thanks

i just did mine about a month ago the cruch sleve is a bitch to crush it took two of us with 4ft breaker bars to crush mine jsut rember the pre-load gets tight verry fast. the setup should go pinion gear, shim,inner bearing, crush sleve, outer bearing, shim,seal, dust sheld, flange, nut. pm me if you have any questions.
