Worst case is you would have to set up the gear pattern again if the carrier is replaced, but you can definitely reuse the gears you have.

If they try to feed you some line about how you will need a new ring and pinion, its all BS. If anything while you are in there, check the spider gears since those usually chip and crack long before the ring and pinion.

also make sure they set it up right or it will whine.

tru trac DOES NOT want you to use synthetic gear oil in there units, unless they decided to very recently, i just went through this a few weeks ago on a warranty job. the first question the asked me was did i use synthetic: i told them NO, they told good cause if i did they were not gonna exchange it

you'll need a master install kit, depending on the miles on the gears and such i would replace all bearings and shims, to be on the safe side plus the crush sleave.
