So i just bought a 9 bolt with 3.45 gears that had munched spider gears. and because there are no replacements easily found i bought a complete 3 series posi carrier off ebay.
Can I just pull the gears off my old carrier and slap em in this one and put it back together? or is there something else I'm missing completely?
Thanks,

Well if it were me I would put all new bearings in, check carrier preload, pinion gear depth, gear pattern wear and then slap it together with a new crush sleeve and set pinion gear backlash. Get a complete setup kit from RATECH and it will include all you need minus the tools. You must know that all carriers are not exactly the same, it only takes a few thousands of an inch to make a difference, do it right the first time.
