Does anyone still have instructions on setting up the gears on a late model IFS diff? I'm looking for the proper way to adjust the backlash. I would think that anyone who has bought and done a gear swap would have those instructions from the gear manufacturer. I know how it's done on a conventional diff. I know how to properly preserve existing backlash if it's correct but the clamshell is tricky to recalabrate if the preload and the backlash is screwed up. Some how you have to completely assemble it (in order to check backlash) without over preloading the carrier. I'm sure someone has figured out the easiest way to do it.
