agreed chuckster, do not try to polish the turd. cheapest best route, would be getting some junkyard 4.10 axles and putting autolockers like an aussie in. True story. avoid buying gears if you can, they are a pain to install. And you would most likely have to bring it to a shop, and if you buy an expensive locker now, it will be useless when you go to buy bigger tires, because you wont be able to turn your tires with baby gears. Your jeep would be a dog. lockers have certain gear ratio cutoffs, were they change the carrier in your axle. if you have 3.07 gears right now, even 33s will be tough to turn. I have 33s with 3.55s with an automatic, and its just ok. I also am not running any lockers and I wheel just fine. just my .02.
