ok so i have a arb air locker in the rear end of my 2004 jeep wrangler. i broke an axle shaft and when trying to get the broken shaft out i ran into two problems. first i noticed that the spider gears were chewed up a bit and also the carrier center shaft that held the spider gears would not come out. i was able to get it out but i wrecked it in the process. here is my question. can i replace those gears and where can i find a rebuild kit. everywhere i have looked doesnt seem to have just the spider gears. can any spider gears that will fit in that carrier go in?
