im going to regear my 2000 tj 4.0. im running 33s with a 6" suspension with a dana 30 in the front and 35 rear. i have already bought my rear set of gears 4.56. now i just need the front set and im going to install them, ive seen threads that say i will need new carriers and some say i won't. everything in my axles is stock as far as i know. is there anything else i might need to be ready for and how will i know if i need a new carrier. im not looking to have a pro do my gears because for some reason everyone in my area want 1200 or more to do the gears, and im also rebuilding my motor right now so i cane get the jeep to anyone anyway. some help would be greatly appreciated even better if anyone in the area would be able to help me out

Before you do that, do you research! I paid somebody to do my gears last time, but I really want to learn the innards of an axle real well just because. There is a great read/procedure below for doing your own. The down side to doing your own is, is that you warranty your own stuff. Screw it up once and you pretty much paid for somebody else to do it.

If your gears are 3:07, which I'm sure they probably are, you will need a different carrier to go to 4:56. Are you using new gears or used gears? You will also need a master rebuild kit and some specialized tools. That is the VERY SHORT version. Most people will tell you not to. Whatever, it's your Jeep, but know the consequences if you screw it up!

you are a life saver, thats exactly what i needed. my gears are brand new, i bought G2 ring and pinion and also the G2 master install kit. i planned on doing my research before i started pulling anything apart, i know that i will need the magnetic dial indicator which i already have. i know its risky doing it myself but so is anything you do on your own really, as long as i pay attention and take my time i dont think ill have too much trouble. the only thing thats throwing me is how do i know if i need a new carrier, will the new ring not fit on it or am i looking for something else

What gears do you have in it now? IIRC the carrier break is 3:73 and up. That means if you have 3:07's and you want to go to 4:56's, you would have to get the correct carrier.
